Our primary objective is to gain a quantitative understanding of how the shaft’s radius influences the relationships between force and displacement, as well as between force and delamination areas. These relationships...

..., there is a delamination between two unidirectional carbon fiber polymer-reinforced plies with fibers in the 0 deg and 90 deg directions. Failure criteria for these materials have been presented previously. In this study, invariant parameters are used in the failure criteria. It is seen that the invariant length parameter...

... buckling of an unbonded section is a necessary, but not sufficient, condition for delamination. For that configuration, buckling occurs at the Euler buckling load of a fixed–fixed plate. Although the present study does not include friction or tangential interface stresses, the onset of buckling should...
