Abstract
Experimental evidence suggests that the complete stress-strain history has to be considered as a basis for constitutive modeling if concrete is subjected to high loading rates. An uniaxial dynamic constitutive law for concrete is presented. The uniaxial theory is extended towards the general three-dimensional case. The proposed dynamic continuum damage law as well as the uniaxial theory is verified on split Hopkinson bar tests with different load histories. 1 Introduction The influence of the strain rate on the stress rate in concrete is important in all design situations involving short-duration, high amplitude impulsive loads, e.g. in accidental explosions and vehicle, railway or airplane impact on structures like bridges, offshore platfor
