Continuum Damage-Healing Mechanics with Introduction to New Healing Variables [PDF]
In this study, damage and healing mechanisms are discussed in detail with special emphasis given on two new healing variables. They are introduced in terms of healing variable based on area and healing variable based on elastic stiffness.

Investigation of continuum damage mechanics model without element size sensitivity
A discontinuous material behavior such as ductile fracture and fatigue failure is predicted actively in various fields by FEM. There is continuum damage mechanics as a method to evaluate the discontinuous material behavior in a framework of continuum ...

A Modified Fatigue Damage Model for High-Cycle Fatigue Life Prediction
Based on the assumption of quasibrittle failure under high-cycle fatigue for the metal material, the damage constitutive equation and the modified damage evolution equation are obtained with continuum damage mechanics.

Combining damage and fracture mechanics to model calving [PDF]
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.

A continuum damage mechanics-based approach for the high cycle fatigue behavior of metallic polycrystals [PDF]
International audiencePolycrystalline elasto-plasticity models provide a general framework for investigating the effect of microstructural heterogeneities (e.g. grains, inclusions, pores) on the high cycle fatigue behavior of metallic materials.

Springback Modeling in L-bending Process Using Continuum Damage Mechanics Concept
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 ...
