| Abstract: | The object of this work is to study experimetally the mechanism of delamination buckling failure in a laminate with a single elliptic, or rectangular, or triangular delamination located neer one surface. Under tension or compression loading the ralationships batween delamination buckling strain εc and various parameters of parant Laminate and sublaminata.as well as the delamination growth direction, are investigated. |
