- Abstract
- A plasticity model was developed to predict the behavioral characteristics of concrete in multiaxial compression. To
extend the applicability of the plasticity model to concrete in various stress states, a new model that uses multiple failure
criteria was attempted. A stress was decomposed into one volumetric and two deviatoric components orthogonal to
each other. Independent failure criterion was provided for each stress component. To satisfy the three failure criteria,
the plasticity model using multiple failure criteria was implemented. To describe dilatancy due to compressive damage,
a non-associative flow rule was proposed. The proposed model was compared with various existing test results. The
comparisons show that it predicted most of the experimental results well by applying the three independent failure
criteria.
