Dynamic and impact response of damaged laminated composite plates

Abstract

In the present investigation, a finite element analysis procedure is developed to predict the initiation and propagation of damages as well as to analyse damaged laminated composite plates under forced vibration and impact loads. Isoparametric quadratic plate bending element (nine‐noded rectangular) based on Mindlin plate theory is used to develop the FE codes for the present analysis. A phenomenological damage model assuming the effective stress concept is used to represent the damage of a lamina. The initiation and progress of damage due to forced vibration and low velocity impact are studied for different impactor velocities.
