Abstract

Phase Measurement Interferometry is introduced as an effective approach for the process of measuring crack growth in concrete. The particular mode of cracking of concrete highlighted in this chapter is caused by composite action between reinforcing bars and concrete. The influence of specimen cross-section size and geometry on the interface stresses and bond slip is evaluated. The measured crack length and crack opening and a finite element material model are used in a hybrid experimental/numerical approach to evaluate the unknown normal component of traction at the interface of concrete and rebar.
