N2 - In this paper, the damage progression in laminates fabricated by unidirectionally arrayed chopped strands (UACS) with newly designed slit distribution patterns under tension is simulated based on a multiscale analysis. The multiscale analysis includes a homogenization analysis and a multiscale damage progression analysis of a microscopic region and a macroscopic region. The elastic constants of the laminas used in the macroscopic region are calculated by the homogenization analysis. The silt distribution patterns are exactly modeled in the microscopic region. Cohesive interface element and maximum stress criterion are employed for the simulation of the progression of delamination and other failure modes in the laminates, respectively.
