Crack Patterns Resulting from High Strain-Rate Tests on Concrete
Surface crack patterns were obtained for compression of small concrete specimens at high strain rates in a Split-Hopkinson pressure bar (SHPB). Visible macrocracks were not discernible until the peak stress of the stress-strain curve. The peak stress and associated strain increase with increasing strain rate. Crack density (mm2/mm3) when plotted versus strain was found to increase very fast initially and then become asymptotic to a linear function of strain....
