Davila, C.G. Faculty Civil Engineering and Geosciences Department Structural Engineering Date 2012-06-24 Abstract This study aims to bridge the gap between classical understanding of transverse cracking in [0/90]s laminates and recent computational methods for the modeling of progressive laminate failure. Specifically, the study investigates under which conditions a three-dimensional model with cohesive cracks can reproduce the in situ effect for the ply strength. Subsequently, it is shown that it is possible to reproduce matrix cracking with a single element across the thickness of the ply, provided that the interface stiffness is properly selected. By using an interface stiffness that is inversely proportional to the ply thickness, a shear lag deformation is achieved that is equivalent to the opening deformation of a transverse matrix crack.
