The analysis of plane and axisymmetric problems with concrete-like material behavior is discussed; the weak tensile strength and crushing and cracking behavior are considered. The concrete is treated as a linear elastic, plastic, strain-hardening, and fracture material. The stress--strain relations are first stated in matrix form for the general case of three-dimensional stress states and then reduced to the special cases of plane stress, plane strain, and axisymmetric stress conditions, suitable for use in finite-element analysis. The numerical analysis is obtained within the framework of the finite-element method and a step-by-step integration procedure. The method is applied to the punch-indentation problems of concrete and metal blocks under plane strain conditions. Comparisons between analysis and experiment are made. 8 figures.
