Abstract�� To analyze the buckling of elliptical face-core delaminating in composite sandwich plates, a two-dimensional elastic foundation model was established. A displacement function was considered to describe the buckling shapes. By taking the effects of hygrothermal conditions, of the core and of the composite adjacent to delaminating location into account, Reyleigh-Ritz energy method was used to predict the critical buckling load, as a function of composite material, laying angle and hygrothermal condition.
Keywords�� elastic foundations   environmental effect   laminates   face-core delaminating   hygrothermal conditions
