Constitutive Model for Concrete:An Overview

In the last three decades, the constitutive modelling of concrete evolved considerably. This paper describes various developments in this field based on different approaches such aselasticity, plasticity, continuum damage mechanics, plastic fracturing, endochronic theory,microplane models, etc. In this article the material is assumed to undergo small deformations. Only time independent constitutive models and the issues related to theirimplementation are discussed.
