Intralaminar cracking during cyclic loading in laminates with distributed failure stress in 90-plies

Methodology for cracking evolution simulation in 90-plies during cyclic loading is suggested this paper. It includes using low crack density (where the neighboring cracks do not interact with each other) data from quasi-static and testing (at one load) to determine parameters Weibull transverse failure stress distribution generalized fatigue. Then, Monte Carlo process used assign elements 90-ply. In model, of element degrades number cycles a appears when becomes equal element, calculated computationally efficient analytical method. The model successfully predict whole range. test at load sufficient damage different load. results suggest that dependence on slightly underestimated shape parameter fatigue may be higher than tests. Therefore, tests least two levels are recommended reliable predictions.
