Dynamic response of pulse loaded laminated composite cylinders

Abstract A finite difference solution is presented for elastic wave propagation in laminated composite hollow tubes under axial plane strain, subjected to a radially symmetric pressure pulse at the inner surface. The solution is applied to two-layered cross-ply and angle-ply AS4/3501-6 graphite/epoxy cylinders, and to homogeneous monoclinic cylinders. The effects of pulse time duration, stacking sequence, ply angle and stiffnesses on the resulting displacement, stresses (radial, hoop, axial and shear) and dynamic stress concentration factor are studied.
