| Abstract Scope |
Void growth is an important deformation and damage mechanism in metals under extreme conditions and is dependent on the deformation of the material surrounding the voids. Recent developments in fast Fourier transform (FFT)-based modeling have allowed for faster and more thorough studies of grain-scale effects on void growth. The goal of this work is to understand the role of crystallography on void growth in FCC metals, and compare and cross-validate FFT-based and finite element (FE)-based models to predict crystallographic effects on void growth. To this end, voids in single crystals and polycrystals were simulated using a dilatational/crystal plasticity model implemented in an FFT-based solver (DVPFFT), as well as in its FE equivalent. This talk will discuss the developments made in both models, as well as the effect of crystallography on void growth, including the differences between single crystal and polycrystal materials. |
