Abstract : Recent research in structural concrete under static and dynamic loading has been moving toward the development of three-dimensional stress-strain relations based on the principles of plasticity as well as elasticity. Although significant progress in this area has been made in recent years, no unified treatment of the various existing mathematical models of concrete has been attempted from which a comprehensive elastic-plastic-fracture stress-strain relationship for concrete can be formulated. This unified approach is attempted in the present work. In this theoretical development, the five-parameter failure surface of William-Warnke model, the technique of mixed hardening for cyclic loading, the concept of crushing coefficient and the dual criterion for crushing, cracking, and mixed types of failure of concrete will be considered as the basis for the comprehensive development.
