Ultimate axial load capacity of a delaminated beam-plate

摘要: The paper presents elastic buckling and postbuckling analysis of an axially loaded beam-plate with across-the-width delamination symmetrically located at arbitrary depth. It is found that, for a relatively short thick delamination, the load delaminated plate close lower bound ultimate axial capacity. In case slender can be considerably greater than load, while failure may or not governed by growth. energy-release rate associated growth systematically computed various combinations length load. resulting curves determine possibility stability characteristics provide basis finding Nomenclature = half-length thickness =a/t a/h forces bending moments w transverse deflections stiffnesses Young's modulus in direction amplitude deflection h / t Pi Mf u, v,
