text: AbstractComprehensive data understanding
is a key success driver for data analytics projects. Knowing the characteristics
of the data helps a lot in selecting the appropriate data analysis techniques.
Especially in data-driven product planning, knowledge about the data is a necessary
prerequisite because data of the use phase is very heterogeneous. However, companies
often do not have the necessary know-how or time to build up solid data understanding
in connection with data analysis. In this paper, we develop a methodology to organize
and categorize and thus understand use phase data in a way that makes it accessible
to general data analytics workflows, following a design science research approach.
We first present a knowledge base that lists typical use phase data from a product
planning view. Second, we develop a taxonomy based on standard literature and
real data objects, which covers the diversity of the data considered. The taxonomy
provides 8 dimensions that support classification of use phase data and allows
to capture data characteristics from a data analytics view. Finally, we combine
both views by clustering the objects of the knowledge base according to the taxonomy.
Each of the resulting clusters covers a typical combination of analytics relevant
characteristics occurring in practice. By abstracting from the diversity of use
phase data into artifacts with manageable complexity, our approach provides guidance
to choose appropriate data analysis and AI techniques.

text: Recent studies have revealed that 87 % to 96 % of the Android apps using cryptographic
APIs have a misuse which may cause security vulnerabilities. As previous studies
did not conduct a qualitative examination of the validity and severity of the
findings, our objective was to understand the findings in more depth. We analyzed
a set of 936 open-source Java applications for cryptographic misuses. Our study
reveals that 88.10 % of the analyzed applications fail to use cryptographic APIs
securely. Through our manual analysis of a random sample, we gained new insights
into effective false positives. For example, every fourth misuse of the frequently
misused JCA class MessageDigest is an effective false positive due to its occurrence
in a non-security context. As we wanted to gain deeper insights into the security
implications of these misuses, we created an extensive vulnerability model for
cryptographic API misuses. Our model includes previously undiscussed attacks in
the context of cryptographic APIs such as DoS attacks. This model reveals that
nearly half of the misuses are of high severity, e.g., hard-coded credentials
and potential Man-in-the-Middle attacks.

text: In the course of digitalization, digital platforms are unleashing their full
disruptive potential and are already dominating the first industries (e.g., hotel
industry). As a result of this success, more and more companies want to build
their own platforms and participate in the success. However, building and operating
a digital platform involves multiple challenges and most of such ambitions fail.
Since most digital platforms fail, strategic leadership of digital platforms must
consider both success factors and reasons for platform failure. For this purpose,
we conducted a systematic literature analysis and identified 24 success as well
as failure factors in 9 dimensions. From a scientific perspective, the article
provides a structured analysis of success and failure factors of digital platforms,
which previously did not exist in literature. Practitioners can use the resulting
knowledge base to successfully manage platform activities and avoid pitfalls.

text: "Lightweight construction has increasingly become the focus of scientific
research in recent years, not least due to\r\nthe constantly increasing fuel price,
which is a key factor in the economic viability of many companies. In this\r\nrespect,
the use of hybrid structures, made of dissimilar materials offers many advantages.
However, such hybrid\r\nstructures often have undesirable side effects. For example,
brittle intermetallic phases are formed when\r\naluminum and steel are welded.
Clinching as a mechanical joining process does not produce such intermetallic\r\nphases
since the connection is realized through form and force closure. In this process,
a punch passes through\r\ntwo or more sheets and forms them into a permanent joint
in a die. In the present work, the corrosion phenomena\r\nof an aluminum-steel
clinched joint have been investigated by both experiments and numerical simulations
in\r\norder to explain the superior fatigue behavior of pre-corroded joints. Therefore,
the clinched joints have been\r\ncorroded by a three-week salt-spray test. In
addition, the electric potential and the von Mises stress are calculated\r\nunder
the assumption of a static loading. The results of both experiments and numerical
simulations can explain\r\nthe improvement in the fatigue behavior of the corroded
specimens. This phenomenon can be attributed to the\r\naccumulation of corrosion
products in small gaps between the joined metal sheets."

text: Clinching is the manufacturing process of joining two or more metal sheets
under high plastic deformation by form and force closure without thermal support
and auxiliary parts. Clinch connections are applicable to difficult-to-join hybrid
material combinations, such as steel and aluminum. Therefore, this technology
is interesting for the application of AISI 304 components, as this material is
widely used as a highly formable sheet material. A characteristic feature of AISI
304 is its metastability, i.e., the face-centered cubic (fcc) γ-austenite can
transform into a significantly stronger body-centered cubic (bcc) α’-martensite
under plastic deformation. This work investigates the effect of heat treatment—a
process that involves the formation of an oxidation layer on the sheet surface—on
the forming process during joining and the resulting mechanical properties of
clinch joints made from AISI 304. For this purpose, different joints made from
non-heat treated and heat-treated sheets were examined using classical metallography
and advanced SEM techniques, accompanied by further investigations, such as hardness
and feritscope measurements. The shear tensile strength was determined, and the
fracture behavior of the samples was investigated. Clear influences of heat-treatment-induced
surface roughness on the joint geometry and strength were observed.

text: The trend towards lightweight design, driven by increasingly stringent emission
targets, poses challenges to conventional joining processes due to the different
mechanical properties of the joining partners used to manufacture multi-material
systems. For this reason, new versatile joining processes are in demand for joining
dissimilar materials. In this regard, pin joining with cold extruded pin structures
is a relatively new, two-stage joining process for joining materials such as high-strength
steel and aluminium as well as steel and fibre-reinforced plastic to multi-material
systems, without the need for auxiliary elements. Due to the novelty of the process,
there are currently only a few studies on the robustness of this joining process
available. Thus, limited statements on the stability of the joining process considering
uncertain process conditions, such as varying material properties or friction
values, can be provided. Motivated by this, the presented work investigates the
influence of different uncertain process parameters on the pin extrusion as well
as on the joining process itself, carrying out a systematic robustness analysis.
Therefore, the methodical approach covers the complete process chain of pin joining,
including the load-bearing capacity of the joint by means of numerical simulation
and data-driven methods. Thereby, a deeper understanding of the pin joining process
is generated and the versatility of the novel joining process is increased. Additionally,
the provision of manufacturing recommendations for the forming of pin joints leads
to a significant decrease in the failure probability caused by ploughing or buckling
effects.

text: Deformation of continuous fibre reinforced plastics during thermally-assisted
forming or joining processes leads to a change of the initial material structure.
The load behaviour of composite parts strongly depends on the resultant material
structure. The prediction of this material structure is a challenging task and
requires a deep knowledge of the material behaviour above melting temperature
and the occurring complex forming phenomena. Through this knowledge, the optimisation
of manufacturing parameters for a more efficient and reproducible process can
be enabled and are in the focus of many investigations. In the present paper,
a simplified pultrusion test rig is developed and presented to investigate the
deformation behaviour of a thermoplastic semi-finished fiber product in a forming
element. Therefore, different process parameters, like forming element temperature,
pulling velocity as well as the forming element geometry, are varied. The deformation
behaviour in the forming zone of the thermoplastic preimpregnated continuous glass
fibre-reinforced material is investigated by computed tomography and the resultant
pulling forces are measured. The results clearly show the correlation between
the forming element temperature and the resulting forces due to a change in the
viscosity of the thermoplastic matrix and the resulting fiber matrix interaction.
In addition, the evaluation of the measurement data shows which forming forces
are required to change the shape of the thermoplastic unidirectional material
with a rectangular cross-section to a round one.

text: Pin extrusion is a common process to realise pin structures in different geometrical
dimensions for a subsequent joining operation. Nevertheless, the process of pin
extrusion offers process limits regarding sheet thinning as a consequence of the
punch penetration depth into the sheet. Thereby, cracks at the residual sheet
thickness can occur during strength tests, resulting in a failure of the complete
joint due to severe thinning. Therefore, measures have to be taken into account
to reduce the thinning. One possibility is the application of orbital formed tailored
blanks with a local material pre-distribution, which allows a higher sheet thickness
in the desired area. Within this contribution, the novel approach of a process
combination of orbital forming and pin extrusion is investigated. To reveal the
potential of a local material pre-distribution, conventional specimens are compared
with previously orbital formed components. Relevant parameters such as the residual
sheet thickness, the pin height as well as the average hardness values are compared.
The results show a significant positive influence of a local material pre-distribution
on the residual sheet thickness as well as the resulting pin height. Furthermore,
the strain hardening during orbital forming can be seen as an additional advantage.
To conclude the results, the process limits of conventional pin extrusion can
be expanded significantly by the application of specimens with a local material
pre-distribution.

text: 'The 3D shear deformation and failure behaviour of a glass fibre reinforced
polypropylene in a shear strain rate range of γ˙=2.2×10−4 to 3.4 1s is investigated.
An Iosipescu testing setup on a servo-hydraulic high speed testing unit is used
to experimentally characterise the in-plane and out-of-plane behaviour utilising
three specimen configurations (12-, 13- and 31-direction). The experimental procedure
as well as the testing results are presented and discussed. The measured shear
stress–shear strain relations indicate a highly nonlinear behaviour and a distinct
rate dependency. Two methods are investigated to derive according material characteristics:
a classical engineering approach based on moduli and strengths and a data driven
approach based on the curve progression. In all cases a Johnson–Cook based formulation
is used to describe rate dependency. The analysis methodologies as well as the
derived model parameters are described and discussed in detail. It is shown that
a phenomenologically enhanced regression can be used to obtain material characteristics
for a generalising constitutive model based on the data driven approach.'
