Fatigue Delamination Behavior of GFRP Composites under Mixed-Mode I/II Loading [PDF]
Iranian Journal of Chemistry & Chemical Engineering, 1999 Delamination is a severe threat to the wide use of composite laminates in primary structural applications. Delamination grows under fatigue loading and leads to structural failure. Very few studies exist on mixed-mode delamination on carbon fiber however
