  This paper deals with three-dimensional nonlinear finite element analysis of concrete structures. A new three-parameter failure criterion, formulated in terms of three stress invariants, is suggested for plain concrete. The criterion can accurately describe available experimental data throughout the stress range from tensile stresses to high compressive stresses.
