A concise interface constitutive law for analysis of delamination and splitting in composite materials and its application to scaled notched tensile specimens
TL;DR: A concise constitutive law for cohesive interfaces is proposed in this paper, which not only accounts for mixed-mode delamination propagation in composite materials, but also satisfactorily deal with mode ratio change during debonding process.
Mixed-Mode Decohesion Elements for Analyses of Progressive Delamination
TL;DR: In this paper, an 8-node decohesion element with mixed mode capability is proposed and demonstrated at the interface between solid finite elements to model the initiation and propagation of delamination.

Progressive Delamination Using Interface Elements
TL;DR: In this paper, a method for modelling progressive mixed-mode delamination in fiber composites is described, which is incorporated within the non-linear finite element method, and is based on the use of interface elements in conjunction with softening relationships between the stresses and the relative displacements.

Interlaminar interface modelling for the prediction of delamination
Olivier Allix,Pierre Ladevèze +1 more
TL;DR: In this article, a laminate is modelled as a stacking sequence of homogeneous layers and interlaminar interfaces, where the interface is a threedimensional medium the thickness of which is negligible compared to the in-plane dimensions.

Delamination analysis by damage mechanics: Some applications
TL;DR: In this paper, the composite laminate is modeled at a meso scale as a stacking of homogeneous layers connected by interfaces, and both onset of delamination and its propagation on a short distance are predicted.

Modeling Compression Failure after Low Velocity Impact on Laminated Composites Using Interface Elements
TL;DR: In this article, a numerical model for predicting the compression failure of laminated composites containing delamination caused by low velocity impact was developed, which is compatible with twenty-seven node isoparametric hexahedral elements and enables modeling the behavior of the damaged interface.

Analysis of a Laminate with a Postbuckled Embedded Delamination, Including Contact Effects
TL;DR: In this paper, the behavior of a postbuckled embedded delamination was studied using geometrically-nonlinear 3-D finite element analysis, and the analysis showed that the postbuckling deformation can lead to matrix cracking and fiber breakage in addition to delamination growth.
