Current research activities are of a hybrid nature involving experimental investigations of micro- and macro-mechanical properties, numerical and theoretical modelling of inelastic material behaviour, fatigue damage mechanisms and life prediction methodology. The type of materials investigated may be grouped into the categories of fibre reinforced polymers, metal matrix composites, polymers and metals.

The overall objectives of the current research program are to obtain a thorough understanding of the mechanical properties of composite materials under multiaxial loads, to evaluate the strengthening effect of reinforcement under multiaxial stress states and to formulate appropriate constitutive models which can be implemented in a general purpose finite element program to aid in design and analysis of industrial components. A further objective of these studies is to develop a theory to predict fatigue life/long term behaviour of composite materials under multiaxial loading.

Key words: composite materials, fatigue, fracture, reliability
