Frequency-Dependent Cohesive Zone Models for Fatigue

, 2017
This paper is concerned with a new cohesive zone model (CZM) to better describe the effects of rate and cyclic loading. Rate is known to affect the manner in which cracks propagate in materials, yet there presently exists no rate-dependent cohesive model

Modeling plastic deformation of TWIP steel using cohesive zone and crystal plasticity finite element

Materials & Design
In this research, the cohesive zone model-crystal plasticity finite element (CZM-CPFE) method was applied to reveal the influence mechanism of grain boundaries (GBs) and grains on the mechanical properties of fine/ultrafine grained TWIP steels.
