Abstract

Under severe mechanical loading, brittle materials, like concrete, can be described favourably using damage models. In order to determine the vulnerability of reinforced concrete structures submitted to accidental loading, the Centre d'Etudes de Gramat has developed an explicit damage model. This new concrete model uses two internal scalar variables to represent the material stiflhess with opened or closed Inelastic tensile and inelastic compressive strains are introduced. Strain rate effects are also taking into account in order to separately increase the dynamic tensile and compressive material strength. Friction stresses are added to simulate stress strain hysteresis during unloading and reloading path. The Hillerbo
