Abstract
A general constitutive model for concrete is discussed in which the total strain rate is decomposed into elastic, plastic and damage strain rates. The rate equations are formulated for all strain rate portions together with evolution rules for hardening and damage state variables. The coupling effect between damage and plastic deformation is considered by introducing yield and damage surfaces and formulating proper interaction rules. Both axisymmetric and general threedimensional stress states are considered for which monotonic and cyclic loading conditions are assumed. The model is aimed to describe material behavior for a variety of loading histories. Its applicability is illustrated by considering uniaxial, biaxial and triaxial compression with superposed shear stresses.
