It was shown in a previous work by the same authors that the stringent mesh size requirement on cohesive, interface elements, can be alleviated through enrichment of the finite element basis functions. In this paper, some limitations of the enriched

Delamination and matrix cracking are routine damage mechanisms, observed by post-mortem analysis of laminated structures containing geometrical features such as notches or bolts. Current finite element tools cannot explicitly model an intralaminar ma

This article summarizes the work undertaken during the period 2007–2008 by the Materials and Structures task within FLAVIIR. The aim was to examine how much structural testing could be realistically replaced by simulation. The aim was to employ a f

Composite damage modelling with cohesive elements has initially been limited to the analysis of interface damage or delamination. However, their use is also being extended to the analysis of inplane tensile failure arising from matrix or fibre fractu

The effect of impact on static strength and fatigue durability is reviewed. Impacts are categorised in terms of the impact velocity, impacting mass and impact energy. At low-to-medium velocities, delamination damage develops below the impact site wit

This paper addresses the problem of modelling the onset of delamination/debonding in composite structures and then the consequent propagation. A new interface element is designed which embraces both the initiation (strength-based) and the propagation

Two types of sandwich panels with carbon epoxy skins and aluminium honeycomb core were subjected to low velocity impacts and then the damaged panels tested for their compression-after-impact (CAI) strength. One type of panel was found to be a very ro

The development of the next generation of civil and military transport aircraft will inevitably see an increased use of advanced carbon fibre composite material in the primary structure if performance targets are to be met. One concern in this develo

This paper outlines a finite element procedure for predicting the behaviour under low velocity impact of sandwich panels consisting of brittle composite skins supported by a ductile core. The modelling of the impact requires a dynamic analysis that c
