Abstract

The debonding of FRP from concrete substrate is studied using a stochastic finite element simulation of the direct shear test. The instability at final failure in the debonding of FRP from concrete is shown to be the result of snapback. The local variations in the interface fracture properties are shown not to significantly influence the severity of snapback.
