Delamination Growth in Composite Structures under Inplane Compression Loading,
Abstract
An approximate solution to the stress field causing delamination under biaxial loading, where the principal load is compressive, has been developed. It utilizes a Raleigh-Ritz approach for the finite amplitude deflection analysis of a rectangular or elliptical plate which has bending/membrane coupling terms and clamped boundary conditions. The solution as developed determines the complete stress field on the boundary, including the short transverse stress field. This leads to delamination growth trajectories which can be analyzed to establish design criteria to be used to minimize the impact of delamination growth considerations by stacking sequence selection, etc., as well as to maximize the residual strength capabilities of the structure.
