Crack shape studies in brittle porous materials
Abstract
The technique of ultrasonic fractography has been used to study crack interactions in a porous glass. Observations indicate the initial attraction of a crack to the porosity, the change of crack shape as the crack segments to bypass the pores and the production of fracture surface steps as the crack breaks away. This technique has great potential for the study of local changes in crack shape and velocity in brittle composite systems.
