ABSTRACT = {The smeared crack approach (SCA) is revisited to describe post-peak softening in laminated composite materials. First, predictions of the SCA are compared against linear elastic fracture mechanics (LEFM) based predictions for the debonding of an adhesively bonded double cantilever beam. A sensitivity analysis is performed to establish the influence of element size and cohesive strength on the load-deflection response. The SCA is further validated by studying the in-plane fracture of a laminated composite in a single edge bend test configuration. In doing so, issues related to mesh size and their effects (or non-effects) are discussed and compared against other predictive computational techniques. Finally, the SCA is specialized to orthotropic materials. The application of the SCA is demonstrated for failure mechanics of the open hole tension test, where fiber/matrix fracture is predominant and predicted well by the present approach.},
