Mixed-Mode Fracture of Concrete at High Strain Rates.

Abstract

Mixed-mode fracture specimens were tested at quasi-static and impact rate of loading. Laser holographic interferometry, reflection photoelasticity, image processing and high speed photography were used for recording, measurement and analysis of data. Strain fields and crack growth were measured for center notched disk specim?ns. By rotating the notch angle with respect to the loading direction, it was possible to change the failure
