A constitutive relation and failure criterion for concrete material under general three-dimensional stress states has been developed using the work-hardening theory of plasticity. The formulation has all the required properties of concrete and gives a close estimate to experimental stresses for complete general stress states. In order that the results of research be readily usable in the analysis of suboceanic structures such as the large shells proposed for adoption in the Ocean Thermal Energy Conversion program (OTEC), corresponding computer codes must be developed to reflect this material. This report describes the development of the corresponding computer code in the form of a subroutine for the general purpose nonlinear finite element analysis program called NONSAP which was originally developed by the University of California at Berkeley in 1974.
