Experimental investigation on damage evolution in cross-ply laminates subjected to quasi-static and fatigue loading

In this paper an experimental investigation on damage evolution in cross-ply glass fiber reinforced plastic (GFRP) laminates under quasi-static and fatigue loading is presented. Four configurations of lay-up ([02/904]s, [02/902]s, [0/904]s and [0/903/0/903]s) with different thicknesses of cracking plies were selected to study the in-situ behavior in the damage initiation, evolution and saturation. Combined with the imaging features of different...
