Affordable Multi-scale Numerical Simulation of Structures in Anisotropic Plasticity and Damage
摘要
The “reduced texture methodology” enables the numerical modeling of laboratory specimens with mean field polycrystalline plasticity at an affordable cost. It makes it possible to model not only plastic anisotropy, anisotropic hardening and non-proportional loadings but also the various ductile fracture mechanisms observed in metallic alloys: initiation, growth, rotation, flattening and coalescence of microscopic voids, transgranular fracture, secondary voids nucleation at the grain scale and coalescence at the slip system scale. The extension to numerical modeling of processes and structural behavior can be achieved in the longer term.
