Quantitative in situ study of short crack propagation in polygranular graphite by digital image correlation

Abstract:

This paper reports experimental observations that show non-irradiated Gilsocarbon polygranular nuclear graphite fits within the quasi-brittle class of materials. Such materials exhibit a degree of damage tolerance that depends on the stability of cracks that nucleate in the microstructure. Modelling efforts to predict the influence of microstructure on damage tolerance require direct observation of crack nucleation and growth to support them. Here, the technique of digital image correlation w...
