Analysis and prediction of structural response to static or dynamic loading requires
prediction of concrete response tovariable load histories. The constitutive equations for the
mechanical behavior of concrete capable of seeing damage effects or crack growth procedure under
loading/unloading/reloading was developed upon micro-plane framework. The proposed damage
formulation has been built on the basis of five fundamental types of stress/strain combinations,
which essentially may occur on any of micro-planes. Model verification under different
loading/unloading/reloading stress/strain paths has been examined. The proposed model is capable
of presenting pre-failure history of stress/strain progress on different predefined sampling planes
through material. Many of mechanical behavior aspects happen during plasticity such as induced
anisotropy, rotation of principal stress/strain axes, localization of stress/strain, and even failure
mechanism are predicted upon a simple rational way and can be presented.
