VARIATIONAL PRINCIPLE OF HYBRID ENERGY AND THE FUNDAMENTALS OF 3-D LAMINATE THEORY-A NEW APPROACH FOR THE ANALYSIS OF INTERLAMINAR STRESSES IN COMPOSITE LAMINATES

Abstract

Abstract: This paper discusses the discontinuity of stresses and strains atinterlaminar sirfacesof the eomposne laminate and presents a 3-D laminate theory for composite materials.This paper also presents a new type of elastic energy based on the globally continuous variables in laminates, different front the traditional potential energy and complementary energy. Then, a variatinal principle corresponding to the 3-D laminate theory is developed. The theory and the principle could he a basis of verifying the 2-D laminate theory and determining the interlarninar stresses near the free edges.

Key words: two-dimensional hypersonic boundary layer, stability, variable specific heat
