Failure analysis of composite laminate under low-velocity impact based on micromechanics of failure

Previous researches on the impacted composite laminates were mainly carried out according to the macromechanics-based homogenous strength theories, which ignore the local stress nonuniformity and strength difference between the fiber and matrix. In this paper, a new multiscale analysis method which combines the micromechanics of failure (MMF) theory for intralaminar damage and cohesive model for interlaminar failure is proposed. This approach is...
