Popis: A three-dimensional continuum damage model is developed for the prediction of the initiation and propagation of intralaminar damage mechanism. This continuum damage model is implemented using a user-subroutine in finite element software ABAQUS™/Standard and combined with the cohesive zone model for three-dimensional progressive damage analysis of angle-ply [0/α] (α = 90°, 75°, 60°, 45°, 30°, 15°, and 10°) laminated plates subjected to transverse loading. It is found that delamination is the major damage mode in large-angle (α ≥ 30°) laminates while fiber bridging is the dominant damage mode in small-angle (α ≤ 15°) laminates. The damage mode predictions are in good agreement with experimental observations reported in the literature. Matrix cracking within the bottom plies and its interactions with interlaminar damage are found to play an important role in the formation of the final damage modes, shapes, and sizes.
