Numerical model for progressive failure analysis of fibre-reiforced composite laminates
Non-linear FEA code is presented in this study. It simulates the material degradation of individual plies fibre-reinforced composite plates using progressive failure analysis by means of FEA. Initial damage is detected using the ply-by-ply analysis w...

The effect of input pulse shape on stress wave propagation in a thick plate.
The effect geometrical dispersion is that the energy in a wave-packet propagates at different speeds depending on its frequency. It is shown that duration of a wave-packet increases linearly with propagation distance and also that the duration of a w...
