Abstract: This paper presents a constitutive model for concrete in high-rate dynamics. The main feature outlined in this paper concerns the modeling of strength enhancement due to rate effects at the macrolevel of material description. ...

Abstract: This paper presents the application of the material model presented in the companion paper to the structural analysis of tunnels driven according to the new Austrian tunneling method (NATM). On the one hand, two-dimensional ...

Abstract: In this paper, creep and viscous flow are revisited from the standpoint of constitutive modeling of thermo-chemo-mechanical couplings in early-age concrete. Within the framework of closed reactive porous media, creep is ...
