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…
