Abstract

This report provides an overview of predictive models for determining deformation and failure behaviour of toughened adhesives and polymer matrix composites (PMCs_ under monotonic, cyclic and creep loading conditions. The report describes a new model for characterising the behaviour of rubber-toughened adhesives. This model, which accounts for the influence of rubber particle cavitation on the yeild behaviour of adhesives, has been adopted for use with the finite element software package ABAQUS. Modelling non-linear creep in adhesives through the use of a model for time-dependent plasticity is also discussed. Results from failure studies conducted on different adhesives joints under monotonic loading have been included as part of the assessment on the validity of various criteria for predicting failure. The report reviews physics/mechanistic, fracture mechanics and non-mechanistic (i.e. statistical and empirical) based theories that are used to predict the onset and propagation of damage, and subsequent deterioration in thermo-elastic properties of composite laminates. It also includes three-dimensional laminate analysis.
