    Abstract

    The Concrete Damaged Plasticity (CDP) built-in material model available in the Abaqus commercial fnite element software, [1], is widely used for beyond design criteria analyses of reinforced concrete structures within the Abaqus users community. In particular, the CDP model has proven to be versatile enough to be used in beyond design basis earthquake analyses, [2, 3, 4], as well as in benchmark impact test analyses, [5, 6, 7], and full scale airplane crash simulations, [8].
    Originally developed on top of the \Barcelona" yield surface, [9], and later on the isotropic hardening laws proposed by Lee and Fenves, [10, 11], that separate the internal plastic variables into a tensile and a compressive parts, the CDP model in Abaqus enables also feld variable dependent customized approaches. For example, a user enhanced Abaqus CDP model with confinement stress dependent compressive hardening evolution and strain rate dependent tensile
    softening evolution was proposed in [12]. Such custom material models are, indeed, necessary in special applications, in case of the previous example, in hard missile impact simulations.
