Abstract The present investigation focuses on the differences of the buckling behaviour of thin laminated composite cylinders under static axial compression and axial impact. The adopted computational approach is based on the equations of motion, which are numerically solved using a finite element code (ABAQUS/Explicit). Different time histories of pulse loadings are achieved using various masses and velocities of the weight that impacts the cylinder. The influence of load magnitude and duration is studied numerically and the dynamic buckling results are related to the static buckling ones. The numerical results are compared to experiments.
