A Geometrically Regularized Gradient‐Damage Model With Orthogonality‐Based Energy Split for Dynamic Anisotropic Compression‐Shear Fracture

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT This study proposes a novel geometrically regularized gradient‐damage model for simulating dynamic mixed‐mode fracture in orthotropic materials with tension–compression asymmetry. In this model, a thermodynamic framework is formulated by incorporating damage dissipation into internal energy evolution, from which the constitutive relation and ...

Multiscale Prediction of Anisotropic Plasticity in Additively Manufactured Lattices

Advanced Theory and Simulations, Volume 9, Issue 5, May 2026.
A multiscale framework is introduced for predicting the anisotropic elastic‐plastic response of FFF‐printed polymer lattices. By linking filament‐resolved homogenization with the Hill yield criterion, it captures yield onset, strain localization, and bending response across print configurations with high efficiency, revealing how filament architecture ...
