Modelling and simulation methodology for unidirectional composite laminates in a Virtual Test Lab framework
TL;DR: A reliable virtual testing framework for unidirectionally laminated composites is presented that allows the prediction of failure loads and modes of general in-plane coupons with great realism and can be reliably used in for composite materials screening, design and certification.

Progressive failure analysis of 2D woven composites at the meso-micro scale
TL;DR: In this paper, a multi-scale progressive damage modeling strategy was proposed to investigate the damage and failure behaviors of 2D woven composites, and the damage evolution is governed by the material fracture energy during failure.
Journal ArticleDOI
On cohesive element parameters and delamination modelling
TL;DR: In this article, the effect of the cohesive element (CE) parameters on delamination modeling is systematically examined, and the sensitivity of the overall progressive damage process and failure load to the assumed CE strengths and stiffness is studied based on selected examples of fracture and coupon-level tests.

An experimental and numerical investigation into the damage mechanisms in notched composites
TL;DR: In this paper, the effect of size on the tensile strength of composite laminates containing circular holes was investigated, showing that there is a large difference both in failure stress and mechanism due to changes in test configuration.

Failure Prediction Technique for Compression Loaded Carbon Fibre-Epoxy Laminate with Open Holes:
TL;DR: In this article, the inplane compressive fracture behavior of a carbon fiber-epoxy laminate containing a single hole is examined. Failure is due to 0° fibre microbuckling surrounded by delamination.
