text: Laser additive manufacturing processes are used for the production
of highly complex geometric structures due to their high geometric freedom. Additive
manufacturing processes, in particular powder-based selective laser melting, are
used to produce metallic additive manufactured components for the automotive and
aerospace industries. Different materials are often joined together to realize
sustainable lightweight construction. The production of such mixed construction
joints is often realized using mechanical joining technology (e.g. self-piercing
riveting). However, there is currently very little experience with the mechanical
joining of metallic additive manufacturing components. Furthermore, there is insufficient
knowledge about the effects that occur during the mechanical joining of additive
manufacturing components. In this article, a method is presented to investigate
the joinability of additively manufactured components with conventionally manufactured
components using a numerical simulation of the self-piercing riveting process.
For this purpose, the additive manufacturing materials are characterized experimentally,
the simulation model is configured, and the joining process with additive manufacturing
materials is represented in the numerical simulation. Furthermore, the influence
of the building direction on the mechanical properties is shown using miniature
tensile specimens. Besides the configuration of the simulation model, the influence
of heat treatment on the self-piercing riveting process is presented.

text: "AbstractThe use of structured measuring
systems to prevent wall slip is a common approach to obtain absolute rheological
values. Typically, only the minimum distance between the measuring surfaces is
used for further calculation, implying that no flow occurs between the structural
elements. But this assumption is misleading, and a gap correction is necessary.
To determine the radius correction $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
for specific geometries, we conducted investigations on three Newtonian fluids
(two silicon oils and one suspension considered to be Newtonian in the relevant
shear rate range). The results show that $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
is not only shear- and material-independent, but geometry-dependent, providing
a Newtonian flow behaviour in a similar viscosity range. Therefore, a correction
value can be determined with only minute deviations in different Newtonian fluids.
As the conducted laboratory measurements are very time-consuming and expensive,
a CFD-approach with only very small deviations was additionally developed and
compared for validation purposes. Therefore, simulation is an effective and resource-efficient
alternative to the presented laboratory measurements to determine $$\\Delta
r$$\r\n
\ \r\n Δ\r\n r\r\n
\ \r\n
for the correction of structured coaxial geometries even for non-Newtonian fluids
in the future."

text: "Abstract\r\n The accessibility
to rheological parameters for concrete is becoming more and more relevant. This
is mainly related to the constantly emerging challenges, such as not only the
development of high-strength concretes is progressing very fast but also the simulation
of the flow behaviour is of high importance. The main problem, however, is that
the rheological characterisation of fresh concrete is not possible via commercial
rheometers. The so-called concrete rheometers provide valuable relative values
for comparing different concretes, but they cannot measure absolute values. Therefore,
we developed an adaptive coaxial concrete rheometer (ACCR) that allows the measurement
of fresh concrete with particles up to \r\n \r\n
\ \r\n \r\n \r\n
\ \r\n d\r\n
\ \r\n \r\n
\ max\r\n \r\n
\ \r\n =\r\n
\ 5.5\r\n \r\n mm\r\n
\ \r\n {d}_{{\\rm{\\max
}}}=5.5\\hspace{.5em}{\\rm{mm}}\r\n \r\n
\ . The comparison of the ACCR with a commercial
rheometer showed very good agreement for selected test materials (Newtonian fluid,
shear thinning fluid, suspension, and yield stress fluid), so that self-compacting
concrete was subsequently measured. Since these measurements showed a very high
reproducibility, the rheological properties of the fresh concrete could be determined
with high accuracy. The common flow models (Bingham (B), Herschel–Bulkley, modified
Bingham (MB) models) were also tested for their applicability, with the Bingham
and the modified Bingham model proving to be the best suitable ones."

text: Abstract. The combination of incremental sheet metal forming and high-speed
forming offers new possibilities for flexible forming processes in the production
of large sheet metal components of increased complexity with relatively low forming
energies. In this paper, the general feasibility and process differences between
the pulse-driven high-speed forming technologies of electrohydraulic and electromagnetic
forming were investigated. An example component made of EN AW 6016 aluminum sheet
metal was thus formed incrementally by both processes and the forming result evaluated
by an optical 3D measurement system. For this purpose, a forming strategy for
electromagnetic incremental forming (EMIF) was developed, tested and adapted to
the electrohydraulic incremental forming process (EHIF). The discharge energy,
the tool displacement and the pressure field of the forming zone were determined
as relevant parameters for the definition of an adequate tool path strategy. It
was found that the EHIF process is less affected by larger distances between the
tool and the blank, while this is a critical variable for force application to
the component during EMIF. On the other hand, the more uniform pressure distribution
of the EMIF process is advantageous for forming large steady component areas.

text: 'The success of engineering complex technical systems is determined
by meeting customer requirements and institutional regulations. One example relevant
to the automobile industry is the United Nations Economic Commission of Europe
(UN ECE), which specifies the homologation of automobile series and requires proof
of traceability. The required traceability can be achieved by modeling system
artifacts and their relations in a consistent, seamless model—an effect-chain
model. Currently, no in-depth methodology exists to support engineers in developing
certification-compliant effect-chain models. For this purpose, a new methodology
for certification-compliant effect-chain modeling was developed, which includes
extensions of an existing method, suitable models, and tools to support engineers
in the modeling process. For evaluation purposes, applicability is proven based
on the experience of more than 300 workshops at an automotive OEM and an automotive
supplier. The following case example is chosen to demonstrate applicability: the
development of a window lifter that has to meet the demands of UN ECE Regulations
R156 and R21. Results indicate multiple benefits in supporting engineers with
the certification-compliant modeling of effect chains. Three benefits are goal-oriented
modeling to reduce the necessary modeling capacity, increasing model quality by
applying information quality criteria, and the potential to reduce costs through
automatable effect-chain analyses for technical changes. Further, companies in
the automotive and other industries will benefit from increased modeling capabilities
that can be used for architecture modeling and to comply with other regulations
such as ASPICE or ISO 26262.'

text: The development of autonomous vehicles and their introduction in urban traffic
offer many opportunities for traffic improvements. In this paper, an approach
for a future traffic control system for mixed autonomy traffic environments is
presented. Furthermore, a simulation framework based on the city of Paderborn
is introduced to enable the development and examination of such a system. This
encompasses multiple elements including the road network itself, traffic lights,
sensors as well as methods to analyse the topology of the network. Furthermore,
a procedure for traffic demand generation and routing is presented based on statistical
data of the city and traffic data obtained by measurements. The resulting model
can receive and apply the generated control inputs and in turn generates simulated
sensor data for the control system based on the current system state.

text: The current investigation shows the feasibility of 316L steel powder
production via three different argon gas atomisation routes (closed coupled atomisation,
free fall atomisation with and without hot gas), along with subsequent sample
production by laser powder bed fusion (PBF-LB). Here, a mixture of pure Fe and
atomised 316L steel powder is used for PBF-LB to induce a chemical composition
gradient in the microstructure. Optical microscopy and μ-CT investigations proved
that the samples processed by PBF-LB exhibit very little porosity. Combined EBSD-EDS
measurements show the chemical composition gradient leading to the formation of
a local fcc-structure. Upon heat treatment (1100 °C, 14 h), the chemical composition
is homogeneous throughout the microstructure. A moderate decrease (1060 to 985
MPa) in the sample’s ultimate tensile strength (UTS) is observed after heat treatment.
However, the total elongation of the as-built and heat-treated samples remains
the same (≈22%). Similarly, a slight decrease in the hardness from 341 to 307
HV1 is observed upon heat treatment.

text: "This paper reveals the 3D character of the intermetallic layer at the aluminum–steel
interface which pops\r\nup above the original sample surface during annealing.
Popping out of the intermetallics was proven using\r\natomic force microscopy.
The phase expands out of the plane due to the exothermic formation of the Al5Fe2\r\nphase
and the feasibility of surface diffusion. Milling by a focused ion beam enabled
the comparison of the\r\nchemical composition of the surface layer with the bulk
interface, showing no difference. The growth direction\r\nis both towards aluminum
and steel — the main diffusion flux is from aluminum towards steel, and the new\r\nintermetallic
phase emerges at the steel side. The shortage of Al atoms causes a shift of the
intermetallic as a\r\nwhole towards aluminum."

text: "AbstractThree prominent low order implicit
time integration schemes are the first order implicit Euler-method, the second
order trapezoidal rule and the second order Ellsiepen method. Its advantages are
stability and comparatively low computational cost, however, they require the
solution of a nonlinear system of equations. This paper presents a general approach
for the construction of third order Runge–Kutta methods by embedding the above
mentioned implicit schemes into the class of ELDIRK-methods. These will be defined
to have an Explicit Last stage in the general Butcher
array of Diagonal Implicit Runge–Kutta (DIRK) methods,
with the consequence, that no additional system of equations must be solved. The
main results—valid also for non-linear ordinary differential equations—are as
follows: Two extra function calculations are required in order to embed the implicit
Euler-method and one extra function calculation is required for the trapezoidal-rule
and the Ellsiepen method, in order to obtain the third order properties, respectively.
Two numerical examples are concerned with a parachute with viscous damping and
a two-dimensional laser beam simulation. Here, we verify the higher order convergence
behaviours of the proposed new ELDIRK-methods, and its successful performances
for asymptotically exact global error estimation of so-called reversed embedded
RK-method are shown.\r\n"

text: "Abstract\r\n Background\r\n
\ Occupational health interventions for leaders are underrepresented
in small and medium-sized enterprises (SMEs). When creating and developing effective
occupational health interventions, identification of the specific needs of the
target group is regarded as an essential step before planning an intervention.
Therefore, the aim of this study was (1) to examine the subjectively experienced
work-related stressors of leaders in small and medium-sized IT and technological
services enterprises, (2) to explore coping behaviors leaders use to deal with
the experienced work-related stressors, (3) to investigate resources supporting
the coping process and (4) to identify potentially self-perceived consequences
resulting from the experienced stressors.\r\n \r\n
\ Methods\r\n Ten
semi-structured interviews with leaders in small and medium-sized IT and technological
services enterprises were conducted. The interviews were transcribed and analyzed
with content-structuring qualitative content analysis in accordance to Kuckartz.\r\n
\ \r\n Results\r\n
\ Leaders in small and medium-sized IT and technological
services enterprises experience various stressors caused by work organization
as well as industry-related stressors and other work-related stressors. To address
the experienced stressors, leaders apply problem focused coping behaviors (e.g.
performing changes on structural and personal level), emotional focused coping
behaviors (e.g. balancing activities, cognitive restructuring) as well as the
utilization of social support. Helpful resources for the coping process include
organizational, social and personal resources. As a result of the experienced
work-related stressors, interviewees stated to experience different health impairments,
negative effects on work quality as well as neglect of leisure activities and
lack of time for family and friends.\r\n \r\n
\ Conclusion\r\n The
identified experienced work-related stressors, applied coping behaviors, utilized
resources and emerging consequences underpin the urgent need for the development
and performance of health-oriented leadership interventions for leaders in small
and medium- sized IT and technological services. The results of this study can
be used when designing a target-oriented intervention for the examined target
group.\r\n "

text: "Abstract\r\n\t \r\n\t
\ Objective:\r\n\t To systematically review
the impact of choice architecture interventions (CAI) on the food choice of healthy
adolescents in a secondary school setting. Factors potentially contributing to
the effectiveness of CAI types and numbers implemented and its long-term success
were examined.\r\n\t \r\n\t \r\n\t
\ Design:\r\n\t PUBMED and Web of Science
were systematically searched in October 2021. Publications were included following
predefined inclusion criteria and grouped according to number and duration of
implemented interventions. Intervention impact was determined by systematic description
of the reported quantitative changes in food choice and/or consumption. Intervention
types were compared with regards to food selection and sustained effects either
during or following the intervention.\r\n\t \r\n\t \r\n\t Setting:\r\n\t
\ CAI on food choice of healthy adolescents in secondary schools.\r\n\t
\ \r\n\t \r\n\t Participants:\r\n\t
\ Not applicable\r\n\t \r\n\t \r\n\t
\ Results:\r\n\t Fourteen studies were included;
four randomized controlled trials and five each of controlled or uncontrolled
pre-post design, respectively. Four studies implemented a single CAI type, with
ten implementing > 1. Three studies investigated CAI effects over the course
of a school year either by continuous or repeated data collection, while ten studies’
schools were visited on selected days during intervention. Twelve studies reported
desired changes in overall food selection, yet effects were not always significant,
and appeared less conclusive for longer term studies.\r\n\t \r\n\t
\ \r\n\t Conclusions:\r\n\t
\ This review found promising evidence that CAI can be effective in
encouraging favorable food choices in healthy adolescents in a secondary school
setting. However, further studies designed to evaluate complex interventions are
needed.\r\n\t "
