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…
