The purpose of the paper is to investigate the transverse cracking of cross-ply laminates, subjected to uniaxial tensile loading. In the case of quasi-static tests, most cracks, initiated in the 90{degree} plies, cross instantaneously all the test specimen width from edge to edge. In this case, it is possible to use a two-dimensional analysis to investigate the transverse cracking. The paper compares the results obtained by analytical models, finite element analysis and experimental results. During fatigue tests, matrix cracks in 90{degree} plies initiate at the free edges of test specimens and grow slowly across the specimen width. The damage progression can be characterized by the crack distributions in the width of the test specimen. The stress distribution and the stiffness reduction have been evaluated by a three-dimensional finite element analysis.
