Lightweight return-mapping surrogates for multiscale plasticity: a practical guide
Alireza Daneshyar, Leon Herrmann, Stefan Kollmannsberger
This paper presents a practical guide to building lightweight neural-network surrogates for the plastic return-mapping process in concurrent multiscale (FE2) simulations. Rather th…
Full-waveform inversion via the scaled boundary finite element method
Alireza Daneshyar, Stefan Kollmannsberger
We begin by addressing the time-domain full-waveform inversion using the adjoint method. Next, we derive the scaled boundary semi-weak form of the scalar wave equation in heterogen…
A plastic damage model with mixed isotropic-kinematic hardening for low-cycle fatigue in 7020 aluminum
Alireza Daneshyar, Dorina Siebert, Christina Radlbeck +1
The paper at hand presents an in-depth investigation into the fatigue behavior of the high-strength aluminum alloy EN AW-7020 T6 using both experimental and numerical approaches. T…
The Discontinuous Strain Method: accurately representing fatigue and failure
Leon Herrmann, Alireza Daneshyar, Stefan Kollmannsberger
Fatigue simulation requires accurate modeling of unloading and reloading. However, classical ductile damage models treat deformations after complete failure as irrecoverable -- whi…
On the radial discretization of finite element spaces in the scaled boundary finite element method
Alireza Daneshyar, Stefan Kollmannsberger
The scaled boundary finite element method is known for its capability in reproducing highly-detailed solution fields. This, however, is only attainable in those cases where analyti…
