A CORRECTED COHESIVE ZONE MODEL IN THE INTERLAMINAR FRACTURE OF COMPOSITE
In order to consider both material damage of the crack tip and the initial fracture toughness,a corrected cohesive zone model( CZM) that considers the influence of material damage of the initial crack propagation has been proposed. The corrected cohesive

Numerical-Experimental Correlation of Interlaminar Damage Growth in Composite Structures: Setting Cohesive Zone Model Parameters [PDF]
Composite laminates are characterized by high mechanical in-plane properties while experiencing, on the contrary, a poor out-of-plane response.

Finite element simulation of delamination growth in composite materials using LS-DYNA [PDF]
In this paper, a modified adaptive cohesive element is presented. The new elements are developed and implemented in LS-DYNA, as a user defined material subroutine (UMAT), to stabilize the finite element simulations of delamination propagation in ...

Multi-timescale analysis of fatigue crack growth on interfaces via cohesive-zone models [PDF]
The paper describes a new non-linear finite-element formulation to analyse fatigue debonding or delamination, along predefined interfaces, which is multi-scale in time. At the small timescale level, cyclic loading and the related oscillating response are

Testing some implementations of a cohesive-zone model at finite strain [PDF]
This study shows how the results given by a cohesive-zone model at finite strain may depend strongly on its numerical implementation. A two-dimensional four-node cohesive element is considered, which includes several variants depending on a part of the ...

A Moving Cohesive Mesh Formulation to Predict Debonding Phenomena in Layered Structures [PDF]
A new numerical formulation, which combines the Cohesive Zone Model (CZM) approach with the Arbitrary Lagrangian-Eulerian (ALE) methodology to investigate the crack onset and evolution of multilayer composite beams is presented.
