The Concrete Damage Model that is implemented in the LS-Dyna code is capable of simulating the behavior of plain concrete under complex static and dynamic loading conditions. However, the values for the numerous parameters, which are required as an input, are left for the user to provide. In this study the Concrete Damage Model was calibrated for a wide range of strong concretes, using triaxial-compression-test data that were obtained from the literature. In contrast, the adjustment of the parameters of the present model is provided as a function of the unconfined compressive strength of the concrete. Although, not enough validation has been done either in higher pressures or in actual tests, it is evident that the presently calibrated model shows better agreement with published test results than the model currently available in LS-Dyna.
