A predictor-corrector scheme for approximating signed distances using finite element methods
Amina El Bachari, Johann Rannou, Vladislav A. Yastrebov +2
In this article, we introduce a finite element method designed for the robust computation of approximate signed distance functions to arbitrary boundaries in two and three dimensio…

A time-discontinuous elasto-plasticity formalism to simulate instantaneous plastic flow bursts
Mathias Lamari, Pierre Kerfriden, Oguz Umut Salman +3
Plastic flow is conventionally treated as continuous in finite element (FE) codes, whether in isotropic, anisotropic plasticity, or crystal plasticity. This approach, derived from…
