text: "The state of the art shows that PBF-LB/M offers great potential for pressure-loaded
parts, with significant weight reductions and simultaneous optimization of flow
resistance. This study is aimed at applying existing calculation methods for pressure-loaded
parts to additively manufactured pipe structures, considering the two materials
EN AC-43000 (3.2381, AlSi10Mg) and AISI 316L (1.4404, X2CrNiMo17-12-2). For this
purpose, systematic tensile tests are carried out for both materials. In addition,
a statistical evaluation is performed to determine the design-relevant strength
characteristics with a survival probability Ps of 97.5 % for both materials in
the as-built and heat-treated condition.\r\nPipe specimens are manufactured, half
of which are heat treated, geometrically measured and then subjected to a burst
pressure test to experimentally determine the failure-critical internal pressure.
These results are compared with calculated burst pressures. The calculations are
based on the application-relevant methods identified in this study, considering
the strength values determined for the respective material condition. This comparison
is used to assess the suitability of the calculation methods for additively manufactured
pipe structures, based on the materials investigated."

text: Clinched joints with non-rotationally symmetric geometries exhibit
orientation-dependent mechanical behavior that is commonly neglected in structural-scale
simulations. Reuleaux triangle shaped clinched joints, in particular, show pronounced
in-plane anisotropy depending on their orientation. While such effects have been
studied at joint and specimen scale, their relevance at the structural level remains
largely unexplored. In this work, the influence of joint orientation on the bending
response of a joined structure is investigated using numerical simulations. A
simplified joint replacement model based on the *CONSTRAINED_SPR2 point-connector
formulation in LS-DYNA is employed, with parameters calibrated from previously
obtained experimental force displacement data. A hat shaped profile structure
subjected to three-point bending is analyzed in a parametric study considering
variations in joint orientation, joint spacing, and profile geometry. The results
show that joint orientation has little influence during the initial deformation
phase but becomes increasingly significant at larger displacements, where joint
behavior governs load transfer. Orientation dependent effects are found to influence
the global force displacement response and local load redistribution among joints,
with magnitudes comparable to those induced by changes in joint spacing and structural
geometry. The findings confirm that joint orientation effects remain relevant
at the structural level and should be considered in the design of structures assembled
using non-rotationally symmetric clinched joints.

text: Laser Powder Bed Fusion (PBF-LB/M) enables significant performance enhancements
in tool and mold making via the integration of complex, conformal cooling channels.
However, high manufacturing costs of monolithic components and material-specific
defect susceptibility still hinder widespread industrial adoption. Within the
collaborative project WerKo3D, the scaling, process qualification, and structural
design of the novel tool steel Printium 13 were successfully investigated to lower
market entry barriers for additive tooling applications. An industrial batch of
50 kg of Printium 13 powder was produced via vacuum inert gas atomization and
thoroughly characterized. Utilizing a Design of Experiments (DoE) approach on
an SLM 280 system, an optimized process window was established, yielding a relative
density of about 99.99%. Subsequent heat treatment parameterizations revealed
a superior mechanical property profile combining high hardness with enhanced impact
toughness compared to conventional AISI H13 tool steel, alongside ultimate tensile
strengths up to 1,600 MPa. To reduce build times and material consumption, a segmented
shell-core tool design was conceptualized and numerically optimized via coupled
CFD and FEM simulations. The functional demonstrator - a sprue insert for aluminum
die casting - was additively manufactured without cracking, heat-treated, and
finish-machined to final dimensions. Furthermore, a two-day training and knowledge-transfer
program was realized to disseminate design guidelines to industry stakeholders.
The findings validate the complete process chain from powder atomization to crack-free
hybrid tool manufacturing.

text: Um die international und national beschlossenen Klimaziele zu erreichen, müssen
die verkehrsbedingten Emissionen in der Bundesrepublik Deutschland drastisch reduziert
werden. Hierzu bedarf es einer umfassenden Mobilitätswende, welche die Etablierung
emissionsärmerer und effizienterer Mobilitätsformen umfasst. Ein Lösungsansatz
können on-demand Dienste bieten, die den öffentlichen Personennahverkehr bedarfsgerecht
gestalten und so dessen Akzeptanz steigern. Zahlreiche bisher eingeführte on-demand
Dienste mussten jedoch nach Beendigung des Projekt- bzw. Förderzeitraums wieder
eingestellt werden. Maßgebliche Herausforderungen waren die Integration der Dienste
in die bestehenden ÖPNV- und Mobilitäts-Strukturen sowie teilweise damit einhergehende
ökonomische Aspekte. In diesem Beitrag wird eine Methode vorgestellt, welche neben
der Einführung neuartiger Mobilitätsdienste auch die Entwicklung eines nachhaltigen
Mobilitäts-Ökosystems anstrebt. Der Fokus liegt dabei auf ländlich geprägten Regionen
und ihren besonderen Herausforderungen im Bereich des öffentlichen Nahverkehrs.
Die Methode beschreibt ein fünf-phasiges Handlungsschema, in welchem Potenziale
bestehender Strukturen genutzt, Mobilitäts-Stakeholder eingebunden und verhärtete
Mobilitätsverhalten allmählich positiv verändert werden. Anhand der Initiative
Neue Mobilität Paderborn wird aufgezeigt, dass mithilfe der Methode erste Schritte
hin zu einem Mobilitäts-Ökosystem absolviert werden können. Darüber hinaus werden
Einführungsszenarien für die neuartige, sich noch in der Entwicklung befindliche
Mobilitätslösung NeMo.bil in einer Beispielregion erarbeitet.

text: Fibre-reinforced polymers are increasingly used due to their high specific
strength, making them suitable for local sheet metal reinforcement. This allows
improved overall mechanical properties with reduced wall thickness of the sheet
metal part and, thus, lower weight of the components. One of the main focuses
of research into such hybrid structures is on the adhesive properties and the
respective failure behaviour of the interfaces. Generally, the failure behaviour
under the influence of mechanical loads can be divided into adhesive, cohesive
and mixed-mode failure. The correlation between observed failure behaviour and
adhesion properties of the hybrid composite materials is analysed in detail in
this work. The hybrid composite consists of an aluminium sheet of the alloy EN
AW‑6082 T6 and thermoset carbon fibre-reinforced plastic (CFRP) prepreg. The aluminium
sheet was laser pretreated before hybrid production to improve the adhesion properties.
The specimens studied were produced by the prepreg pressing process, in which
the components are cured and joined simultaneously. The influences of the thickness
of the CFRP part, the layup, the fibre orientation at the boundary layer, and
the laser pretreatment parameters on the properties of the hybrid joints were
investigated.

text: 'Abstract. Accurate Finite Element Modeling (FEM) of joints is essential
in the design of complex mechanical systems such as automotive body-in-white (BIW)
structures, as it plays a critical role in evaluating their performance. Although
well-established techniques exist for modeling rotationally symmetric joints,
there remains a significant gap in effectively modeling non-rotationally symmetric
joints. These joints are particularly relevant in the automotive BIW, where they
can better accommodate anisotropic loading conditions. In this study, strategies
for modeling non-rotationally symmetric joints were explored using finite element
simulations in LS-DYNA. The findings demonstrate that discrete beam elements can
capture the anisotropic characteristics of such joints. Two models were tested:
a single-beam model for stiffness periodicity every 90°, and a three-beam model
for stiffness periodicity every 120°. Force responses, stress distribution, and
sheet bending behaviors were analyzed, confirming that discrete beam elements
can accurately represent direction-dependent stiffness. These results establish
a foundation for developing advanced joint modeling strategies in complex mechanical
systems.'

text: To reduce transport-related environmental impacts, innovative mobility system
approaches such as on-demand services are being developed. These can include operating
vehicles that differ regarding their characteristics and application profile from
privately owned cars in motorized individual transport. Studies on life cycle
assessment and life cycle engineering of vehicle lightweight structures are mainly
limited to these privately owned cars and the impact category of climate change.
In this paper, a method for life cycle assessment-based engineering of lightweight
structures in vehicles for various mobility system applications, including on-demand
mobility services, is developed. The method enables the holistic life cycle assessment
of lightweight structures in different mobility system applications considering
parameter changes at the upstream products, component, subsystem, vehicle and
mobility system levels, as well as the integration of results into engineering
activities. A case study is used to show that the vehicle and mobility system
application of lightweight structures can significantly influence their environmental
impacts and the selection of ecologically preferable product designs. The application
in vehicles for on-demand mobility services can lead to an increase in absolute
use stage energy demand and environmental impacts compared to applications in
privately owned vehicles for motorized individual transport. However, normalized
to the transport performance provided, the lifecycle environmental impacts of
structural components in vehicles for on-demand mobility services can be lower
than in vehicles for motorized individual transport. The paper contributes methodically
and with quantitative results to improved decision making in life cycle engineering
activities for lightweight structures in mobility system applications.

text: This paper discusses the influence of joint orientation with non-rotationally
symmetric geometry, on load distribution and structural behavior. The focus is
on understanding how changes in the alignment of individual joints affect the
distribution of load, neighboring joints, and the overall performance of the component.
Lap shear specimens with multiple joints arranged in a line are analyzed to explore
these effects. Simplified models are used to model the joints in finite element
simulations, allowing for efficient yet accurate analysis of the load distribution
and structural response under varying joint orientations. Variations in joint
orientation result in measurable changes in the distribution of forces on adjacent
joints, influencing their behavior and that of the overall assembly. Experimental
validation confirms the numerical results, providing deeper insights into the
interaction between individual joints and their surroundings. This work contributes
to the development of systematic approaches for optimizing the design of components
with non-rotationally symmetric joints. The study highlights the importance of
considering directional properties of joints in designing structural components.

text: As global industries seek to reduce energy consumption and lower CO2
emissions, the need for sustainable, efficient maintenance processes in manufacturing
has become increasingly important. Traditional mold cleaning methods often require
complete tool disassembly, extended downtime, and heavy use of solvents, resulting
in high energy costs and environmental impact. This study presents a novel localized
ultrasonic cleaning process for injection molding tools that enables targeted,
in situ cleaning of mold cavities without removing the tool from the press. A
precisely positioned ultrasonic transducer delivers cleaning energy directly to
contaminated areas, eliminating the need for complete mold removal. Multiple cleaning
agents, including alkaline and organic acid solutions, were evaluated for their
effectiveness in combination with ultrasonic excitation. Surface roughness measurements
were used to assess cleaning performance over repeated contamination and cleaning
cycles. Although initial tests were performed manually in the lab, results indicate
that the method can be scaled up and automated effectively. This process offers
a promising path toward energy-efficient, low-emission tool maintenance across
a wide range of injection molding applications.

text: Over the past decades, the importance of lightweight structures in the aircraft
and automotive industries has steadily increased due to regulations aimed at reducing
global warming. Work hardened steel alloys are commonly used for lightweight applications,
but they face stability issues when the material thickness reaches certain thresholds.
Fiber Reinforced Plastics (FRP) offer a viable alternative due to their high strength-to-weight
ratio, but they are often expensive due to long production cycles and high material
costs. A feasible solution lies in hybrid lightweight designs that utilize expensive
FRP materials only in highly stressed areas, achieving a balance between low mass
and acceptable cost. These hybrid structures are lighter than metal components
and more cost-effective compared to fully FRP structures, without compromising
mechanical properties. This study focuses on producing rotationally symmetrical
hybrid structures using Resin Transfer Molding (RTM) combined with vacuum assistance
in a single-stage process. The research examines the effects of injection pressure,
mold temperature, and the interface between metal and FRP. The mechanical characterization
of these hybrid structures was conducted to assess their performance under torsion,
compression, and interlaminar shear strength (ILSS) loading conditions. The results
indicate that hybrid designs can offer a lightweight alternative without compromising
mechanical properties.
