Elastic plastic analysis of elliptical plates

Abstract

The elastic response of elliptical plates to distributed transverse loading is considered. Resorting to the Haar’s wavelets a numerical algorithm for determination of stress and strain components is developed. The material of the plates is assumed to be an ideal elastic plastic material satisfying corresponding yield condition and associated flow law. Particular problems are solved in the cases of stepped plates and Hill’s and Tsai-Wu materials. Numerical results are presented for one- and two-stepped plates.
