# Concrete damaged plasticity

 The concrete damaged plasticity model in Abaqus: provides a general capability for modeling concrete and other quasi-brittle materials in all types of structures (beams, trusses, shells, and solids); uses concepts of isotropic damaged elasticity in combination with isotropic tensile and compressive plasticity to represent the inelastic behavior of concrete; can be used for plain concrete, even though it is intended primarily for the analysis of reinforced concrete structures; can be used with rebar to model concrete reinforcement; is designed for applications in which concrete is subjected to monotonic, cyclic, and/or dynamic loading under low confining pressures; consists of the combination of nonassociated multi-hardening plasticity and scalar (isotropic) damaged elasticity to describe the irreversible damage that occurs during the fracturing process; allows user control of stiffness recovery effects during cyclic load reversals; can be defined to be sensitive to the rate of straining; can be used in conjunction with a viscoplastic regularization of the constitutive equations in Abaqus/Standard to improve the convergence rate in the softening regime; requires that the elastic behavior of the material be isotropic and linear (see Defining isotropic elasticity); and is defined in detail in Damaged plasticity model for concrete and other quasi-brittle materials. See Inelastic behavior for a discussion of the concrete models available in Abaqus. The following topics are discussed:
