Abstract

A viscoplastic model with damage was developed to describe the mechanical behaviour of plain concrete subjected to sustained multiaxial stresses of high intensity. The model is characterized by inelastic strains due to plasticity and damage and by a second-order damage tensor. The evolution laws for these variables are formulated by extending the proposal of other authors for metals and rocksalt. The procedure to obtain the main model parameters from experiments is also outlined. The reliability of the model was assessed through comparisons with available test results.
