Isogeometric analysis of continuum damage in rotation-free composite shells
A large-deformation, isogeometric rotation-free shell formulation is equipped with a damage model to simulate progressive failure in composites. Four intralaminar modes of failure are considered: Longitudinal and transverse tension, and longitudinal and transverse compression. The proposed methodology is valid in the regime of thin shell structures where damage occurs without significant evidence of delamination. The damage model is extensively validated against experimental data and its use is also illustrated in the context of multiscale composite damage analysis.
