This research investigates the buckling delamination mode of embedded interface cracks in a PZT+Metal+PZT sandwich plate, utilizing the piecewise homogenous body model and the three-dimensional linearized theory of stability loss for piezoelectric materials. An interface rectangular crack is presumed to exist between the layers of the face and the core, with the plate subjected to biaxial uniformly distributed compressive forces acting on the vertical sides of the rectangular sandwich plate. The surfaces of the analyzed interface cracks are presumed to possess negligible initial defects prior to loading, and the progression of these initial imperfections under bi-axial compressive forces is examined. Based on the initial imperfection criterion, the critical buckling pressures for local delamination caused by buckling of the rectangular plate around cracks are determined [1]. When the loading levels are beneath the critical threshold, the crack edges display surface wrinkles. This study seeks to examine and evaluate surface wrinkles about diverse geometric and material aspects.
