Abstract
Understanding the strain-softening response of concrete is important for numerical modeling of the constitutive behavior of concrete. In this study the nature and extent of internal cracking were studied for concrete cylinders subjected to axial strains in the post-peak part of the stress-strain curve. Several testing methods to reduce the end-restraint were evaluated and one that gave essentially homogeneous stress distribution was used for the study. Longitudinal and transverse slices of the specimens loaded to different values of axial strains were examined using petrographic techniques for microcracks.
