【Abstract】 The object of this work is to study experimentally the mechanism of delamination buckling failure in a laminate with a single elliptic,or rectangular, or triangular delamination located near one surface. Under tension or compression loading the relationships between delamination buckling strain εc and various parameters of parent laminate and sublaminatc, as well as the delamination growth direction, are investigated.更多还原
