000003364 520__ $$2eng$$aChen model of plasticity was originally derived for solid materials with different strengths in compression and tension, such as concrete or some types of soil. In this work, it is tried to extend the range of application of the Chen model to hardening concrete. At very early ages the microstructure of concrete is developing very rapidly which means that, once compared with already hardened concrete, the material parameters of the Chen model should be a function of the microstructure evolution. The proposed modification of the Chen model considers this effect in terms of the degree of hydration.This approach is described and all necessary equations and parameters are given. The results of the modified Chen model are compared with experimental results.
