Joshuah Wolper and a team of researchers from the University of Pennsylvania presented a new approach to simulating anisotropic damage.
Basically, the new approach helps simulate complex surfaces in a stunningly realistic way.
"Dynamic fracture surrounds us in our day-to-day lives, but animating this phenomenon is notoriously difficult and only further complicated by anisotropic materials -- those with underlying structures that dictate preferred fracture directions." The team presented AnisoMPM (SIGGRAPH 2020 entry), a novel approach to animating the dynamic fracture of isotropic, transversely isotropic, and orthotropic materials. The new system is said to be based on three core components: a technique for anisotropic damage evolution, methods for anisotropic elastic response, and a coupling approach.
When it comes to anisotropic damage, researchers "adopt a non-local continuum damage mechanics (CDM) geometric approach to crack modeling and augment this with structural tensors to encode material anisotropy."
