On a Correspondence between Mechanical and Thermal Fields in Composites with Slipping Interfacesopic constituents undergoing interface slip and separation, the theorem of virtual work is used to establish a similar relation between the effective thermal tensors and the mechanical concentration factors and constituent properties of the composite.

Fiber Stress Enhancement Due to Initial Matrix Crackingor an idealized two-dimensional composite with widely spaced fibers and with a fiber-matrix interface which is governed by Coulomb friction. It is shown that a stronger interface causes a higher stress concentration at the fiber surface thereby raising the likelihood of premature fiber failure.

Bounds for the Creep Behaviour of Polycrystalline Materialsnds of linear elasticity, are easy to generate for τ̄., and are displayed. The main result, however, is the development of a new upper bound for τ̄., which corresponds to the Hashin-Shtrikman upper bound in the linear case. The derivation makes use of elementary results from convex analysis.

Measurement of Strength of Thin Film Interfaces by Laser Spallation Experimentnique a laser pulse of a high enough energy and a pre-determined length is converted into a pressure pulse of a critical amplitude and width that is sent through the substrate toward the free surface with the coating. The reflected tensile wave from the free surface of the coating pries off the coat

Micromechanical Modelling of Fibre Debonding in a Metal Reinforced by Short Fibres accounts for decohesion by normal separation as well as by tangential separation is used to model failure at the interface. The composite material containing a periodic array of aligned fibres is represented in terms of a unit cell model analysis. The effect of varying fibre aspect ratio and varyin
