Abstract

Acoustic emission was used to measure energy associated with fracture of standard test speci- mens. The goal of the work was to identify ways in which acoustic emission could be used to quantify damage in laboratory specimens for the purpose of tuning damage models. A series of mortar and concrete specimens of different compositions were tested for fracture energy, G while simultaneously being monitored for acoustic 1 emission energy release. Reasonable proportionality between the two quantities was observed, however addi- tional work is required for generality.
