ON SOME VARIATIONAL PRINCIPLES IN ELASTICITY AND THEIR APPLICATION TO THE THEORY OF TWO PHASE MATERIALS
Abstract
The establishment of some variational principles in the linear theory of elasticity and with their application to the determination of the effective moduli o two phase elastic materials is presented. The latter problem in particular and the problem of the determination of effective physical constants of composite materials, in general, received considerable attention. Because of the complexity of the problem, attempts to find effective moduli for such materials were based on simplifying assumptions. A more exact theoretical approach consists of the establishment of bounds on the-265 8174N2 AD-265 818Div. 17 U (TIPTM/SEB) Armament Research and Development Establishment (Gt. Brit.).
