, 2022 Bei der Statik handelt es sich um einen vielschichtigen Begriff, der zumeist ausgeblendet wird und dem sich Kunst-, aber auch Literatur- und Kulturwissenschaftler*innen bislang nur selten explizit widmeten. Im Folgenden wird es um die weitere Aufschlüsselung dieses Begriffs gehen, wobei die Kunst der Avantgarden der ersten Hälfte des 20.

Analysis of effects of material anisotropy on ductile damage using microscopic unit‐cell model
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 4, December 2023., 2023 Abstract It is experimentally observed that the failure in ductile metals is mainly due to the nucleation, growth, and coalescence of micro‐voids as well as micro‐shear‐cracks. Furthermore, plastic anisotropy has significant role in damage and failure behavior of ductile metals.

Investigations on adapted interpolation orders for a mixed isogeometric plate formulation
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 4, December 2023., 2023 Abstract In order to overcome locking effects that especially occur for lower order finite element formulations, different methods can be employed. This can be conducted using mixed formulations or adapted approximation orders, for instance. Hence, in order to tackle shear locking that is caused by non‐matching interpolation degrees in the shear strain

On polymorphic uncertainty modeling in shell buckling
Computer-Aided Civil and Infrastructure Engineering, Volume 38, Issue 18, Page 2632-2647, December 2023., 2023 Abstract Buckling is typically the governing failure mode of thin‐walled shells. In particular, geometric and material imperfections have a major influence on the buckling behavior. Small variations of imperfections have large effects on the load‐bearing behavior.

FE‐NN: Efficient‐scale transition for heterogeneous microstructures using neural networks
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023 Abstract Numerical modeling and optimization of advanced composite materials can require huge computational effort when considering their heterogeneous mesostructure and interactions between different material phases within the framework of multiscale modeling. Employing machine learning methods for computational homogenization enables the reduction of

Characterization of ductile damage and fracture behavior under shear reverse loading conditions
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023 Abstract This paper deals with experimental and numerical analysis of the ductile damage and fracture behavior undergoing biaxial non‐proportional shear reverse loading conditions. In the numerical analysis, an anisotropic cyclic plastic‐damage constitutive model is considered to characterize the damage and fracture behavior.

Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 3, November 2023., 2023 Abstract Computational modeling of the fire‐structure interaction demands the coupling between several models typically implemented in independent simulation software describing distinct physical processes. For instance, in the event of a fire breakout or building on fire, the fire not only increases the temperature of the immediate area but also ...

Ductile damage and failure of thin sheet metals: New biaxial experiments and numerical simulations
Proceedings in Applied Mathematics and Mechanics, Volume 23, Issue 2, October 2023., 2023 Abstract The paper deals with the ductile damage and failure behavior of thin sheet metals under proportional biaxial loading paths. A newly designed specimen is presented and an experimental series with different loading ratios is performed. Corresponding numerical simulations including plastic anisotropy reflect the stress state and enable the ...

International Journal for Numerical Methods in Engineering, Volume 124, Issue 17, Page 3603-3636, 15 September 2023., 2023 Summary A general technique to develop arbitrary‐sided polygonal elements based on the scaled boundary finite element method is presented. Shape functions are derived from the solution of the Poisson's equation in contrast to the well‐known Laplace shape functions that are only linearly complete.

Was macht Mathematik effektiv?
Physik in unserer Zeit, Volume 54, Issue 4, Page 176-183, July 2023., 2023 „Ob ich die Mathematik auf ein Paar Dreckklumpen anwende, die wir Planeten nennen, oder auf rein arithmetische Probleme, es bleibt sich gleich, die letztern haben nur noch einen höhern Reiz für mich”, soll Gauß gesagt haben. Aus unserer Sicht ist es ein Geben und Nehmen auf gleicher Augenhöhe zwischen Mathematik und anderen Wissenschaften.
