Thermodynamically-consistent derivation and computation of twinning and fracture in brittle materials by means of phase-field approaches in the finite element method
[article]
2022
arXiv
pre-print
A computational method is proposed for simulating and informing on controlling failure pattern development in anisotropic brittle solids experiencing extreme mechanical loading. Constitutive equations are derived by using thermodynamics in order to establish a fully coupled and transient fracture mechanics model. A phase-field approach is developed for modeling twinning, fracture, and fracture-induced twinning in single crystals at nanometer length-scale. At the nanoscale, this continuum
