Abstract

The effect of rate of loading on the entire deformation history of concrete materials, including plastic damage, is considered. Energy dissipation in the linear (viscoelastic) range is described. One-dimensional results are presented and comparison is made with experimental results in tension, at different rates, from quasistatic to impact. Introduction A viscoelastic-plastic model in series (i.e. with an additive strain decomposition) was proposed by Panoskaltsis et al. [1], [2] for the description of concrete materials up to and beyond failure, including the effect of rate. The additive decomposition of the strain (as opposed
