A Memory Efficient Adjoint Method to Enable Billion Parameter Optimization on a Single GPU in Dynamic Problems
Leon Herrmann, Tim Bürchner, László Kudela +1
Dynamic optimization is currently limited by sensitivity computations that require information from full forward and adjoint wave fields. Since the forward and adjoint solutions ar…
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…
From ductile damage to unilateral contact via point-wise implicit discontinuity at the infinitesimal element level
Alireza Daneshyar, Leon Herrmann, Stefan Kollmannsberger
Ductile damage models and cohesive laws incorporate the material plasticity entailing the growth of irrecoverable deformations even after complete failure. This unrealistic growth…
