Buckling and post-buckling behavior of elliptical plates: Part II-results

Research output: Contribution to journalArticlepeer-review

Abstract

The large-deflection plate solution developed in Part I is used here to study the buckling and post-buckling deformation and stress characteristics of an ellipticallyshaped surface layer that has been delaminated from a large material body. The economical, yet accurate nature of this solution, together with available graphic routines, has made it possible to present, figuratively, a comprehensive description of the plate behavior. The conditions for a layer-substrate overlap and the variations of membrane and bending stresses along the plate boundary are emphasized. Deformations were induced either by a normal pressure or a biaxial displacement field applied to the plate boundary. Theproblem variables are plate size and shape, details of load biaxiality, and load level.
