Extracting gas from shale rocks is one of the current engineering challenges but offers the
prospect of cheap gas. Part of the development of an effective engineering solution for shale …

Transverse cracking in cross-ply carbon/epoxy and glass/epoxy laminates in tension is
analyzed by means of computational micromechanics. Longitudinal plies were modeled as …

This paper presents a new method suitable for modelling multiple discontinuities within a
finite element. The architecture of the proposed method is similar to that of the phantom …

Digital image correlation is applied to the images of a deforming composite to obtain strain
maps at three length scales: micro-scale (ply level, hundreds of micrometers), meso-scale …

This paper presents the modelling of tensile failure of composites using novel enriched
elements defined based on the floating node method. An enriched ply element is developed …

Voids are an important type of manufacturing defects in fiber-reinforced composites. Matrix
cracking is sensitive to the presence of voids. Although this cracking occurs at the ply scale …

This paper provides an overview of the current approaches to predict damage and failure of
composite laminates at the micro-(constituent), meso-(ply), and macro-(structural) levels …

An accurate characterization of intra-and inter-laminar damage is essential for the prediction
of the damage onset and evolution in composite laminates. This paper presents a discrete …

Abstract The Discrete Ply Modelling (DPM) method, previously applied with success to out-of-
plane loading such as impact or pull-through, is used to model open hole tensile tests …

This document provides an overview of recent accomplishments and lessons learned in the
development of general progressive damage analysis methods for predicting the residual …
