The presence of voids in composite materials reduces the material’s strength, particularly matrix-dominated properties such as short beam shear (SBS) strength. Until now there has been no satisfactory way to reliably predict the effect of voids on

Composite laminate thickness tapering is essential for weight efficient structures. This is achieved by terminating specific plies, but these can in turn act as sites for delamination initiation. One area of importance is the spacing between adjacent

Cohesive interface elements have become commonly used for modelling composites delamination. However, a limitation of this technique is the fine mesh size required. Here, a novel cohesive element formulation is proposed and demonstrated for modelling
