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.
