Numerical analysis of the influence of a nearby fibre on the interface crack growth in composites under transverse tensile load
(European Structural Integrity Society, 2016)
In this paper the interface crack growth associated to the inter-fibre failure under tension is studied by means of a two-fibres BEM model. The influence of the presence of an undamaged secondary fibre on the evolution ...
