This report describes an approach to the prediction of the combined fatigue-creep behaviour of materials without damage that is based on the concept of internal state variables. The approach leads to the decomposition of the strain field into elastic, plastic, reversible anelastic and irreversible creep strain components which are defined for multi-axial states of stress.
The model has been implemented as a user-friendly software system known as LOOP+ which enables users, on defining the parameters that occur in the model, to investigate the effects of their selection on multi-axial materials behaviour. Examples are given of the various types of materials behaviour that can be predicted by the model
