A comprehensive framework for the dynamic buckling analysis of composite shell structures has been proposed based on isogeometric analysis. The influences of cut-outs, the amplitude and duration of step pulse load are studied. In particular, the geometric imperfections can be reconstructed and naturally incorporated into the IGA framework due to the unified NURBS basis adopted.
