“…The aspect of delamination in composites has also received adequate attention in the deterministic domain . Stochastic analysis of composite and sandwich structures considering sourceuncertainty is found to be studied by many researchers including the aspects of multi-scale analysis, optimization and reliability assessment [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57][58][59]. However, the compound effect of delamination and sourceuncertainty has not been investigated yet for the dynamic responses of composite structures.…”
