CONSTITUTIVE MODELING OF CONCRETE BY USING NONASSOCIATED PLASTICITY

An elastic strain-hardening plasitc model for plane stress-state concrete under short-term monotonic loading, based on the theory of nonassociated plasiticity has been developed. As a result, a set of constitutive equations suitable for the incremental finite element analysis has been derived. Characteristics of the model include various yield functions, an isotropic hardening rule, a nonassociated flow rule, and a generalized equivalent stress-strain curve. It has been found that this material model is adequate in describing the plastic behavior of plain concrete. Also, the predictions based on the nonassociated flow rule show very good agreement with the test data, while the results achieved using an associated flow rule are poor, especially in regions of combined high compression with low tension.
