Experimental and numerical investigation of the fracture toughness of Glass/Vinylester composite laminates

Mixed-mode interlaminar fracture behaviour of Glass/Vinylester composite laminate has been investigated numerically and experimentally. In the current study, fracture parameters of this type of material have been obtained in pure mode-I, pure mode-II and mixed-mode loading conditions. For this purpose, the butterfly Arcan specimens were produced with various lengths of delamination as pre-cracks and were tested in various loading conditions. The...
