Combining damage and fracture mechanics to model calving [PDF]
The Cryosphere, 2014 Calving of icebergs is a major negative component of polar ice-sheet mass balance. Here we present a new calving model relying on both continuum damage mechanics and linear elastic fracture mechanics.

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept
Journal of Applied and Computational Mechanics, 2015 Springback is one of the most common and important issues in metal forming area. Due to it depends on variety of parameters, it is hard to predict. Hence, in this paper, the effect of continuum damage mechanics (CDM) based on the Lemaitre isotropic ...

Nonlocal Damage Mechanics [PDF]
Revue Européenne de Génie Civil, 2020 ABSTRACT This paper starts with an overview of models that can provide an objective description of highly localized inelastic deformation. Basic ideas behind the integral and differential formulations of nonlocal models are explained using a simple isotropic damage model as a typical example.
