ProFAST is a novel failure initiation and progressive failure analysis (PFA) method for modeling advanced laminated composite structures, utilizing a fundamental physics based multiscale mechanics model embedded in a non-linear finite element code. The software combines micromechanics, damage mechanics and discrete cohesive zone method (DCZM) elements, accounting for all possible physics-based failure mechanisms and their interactions, including both in-plane and out-of-plane effects. The micromechanics models include fiber kinking, buckling and cohesive failure in resin-rich interfaces to predict failure initiation and and progressive failure. In addition, probabilistic analysis capability is incorporated into the PFA methodology to account for material variability and manufacturing inconsistencies.
