Dynamic analysis of multiple delaminated composite twisted plates

The present paper deals with the finite element dynamic analysis of delaminated composite twisted plates based on a simple multiple delaminated model. Eight‐noded isoparametric quadratic elements are used to develop the finite element analysis procedure. Composite plates are assumed to contain both single and multiple delaminations. To investigate the dynamic behaviour of delaminated twisted plates, numerical results for free vibration, forced vibration and impact response are generated by varying the size and location of delaminations as well as the stacking sequence and other geometrical parameters.
