Simulating ice-shelf extent using damage mechanics
Journal of Glaciology, 2022 Inaccurate representations of iceberg calving from ice shelves are a large source of uncertainty in mass-loss projections from the Antarctic ice sheet. Here, we address this limitation by implementing and testing a continuum damage-mechanics model in a ...

Basic concepts and models in continuum damage mechanics [PDF]
, 2007 In this paper, we present some basic elements of macroscopic modelling of damage. We then recall the general approach of continuum damage based on the thermodynamics of irreversible processes and its application to isotropic damage modelling.

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 ...

A Stress Tensor-based Failure Criterion for Ordinary State-based Peridynamic Models [PDF]
Journal of Applied and Computational Mechanics, 2022 Peridynamics is a recent nonlocal theory of continuum mechanics that is suitable to describe fracture problems in solid mechanics. In this paper, a new failure criterion based on the stress field is developed by adopting the damage correspondence model ...

Delamination Prediction by Continuum Damage Mechanics [PDF]
, 1999 The present study describes the basic principles of a general damage approach for laminates and demonstrates its prediction possibilities for simulating the complete fracture phenomenon in the case of the initiation and propagation of delamination. In this paper, the Damage Mechanics Approach is presented to solve delamination problems such as the ...
