TL;DR: In this article, the authors propose to solve the dependency of the softening elastoplastic models using the meshless Finite Points Method, which allows enriching the governing equations using gradient's plasticity and introducing an internal length scale parameter at the material model to objectify the solution.
Abstract: The softening elastoplastic models present an unsuitable behavior after reaching
the yield strength: unbounded strain localization. Because of the material
instability, which is reflected in the loss of ellipticity of the governing partial
differential equations, the solution depends on the discretization.
The present work proposes to solve this dependency using the meshless Finite
Points Method. This meshfree spatial discretization technique allows enriching
the governing equations using gradient’s plasticity and introducing an internal
length scale parameter at the material model in order to objectify the solution.
