摘要：

It is shown that strain localization occurring in the positive hardening regime of axially-symmetric compression stress states, may be modeled through a proper choice of the yield function and flow-mode, in the context of the infinitesimal rate-independent non-associative elastoplasticity. In this way, it becomes possible to interpret the results of the uniaxial compression tests carried out on concrete and fiber-reinforced concrete specimens.
