Abstract
In this study, by employing the edge cracked semicircular disc under uniform (ECSD(UC)) and calculating the shape factor, the toughness of brittle materials under uniform compressive load has been quickly evaluated. Samples, on the loading location and the support, under angle β changing from 0 to 10 degrees, with the crack length (a) changing from 1 to 29 mm and the thickness (t) changing from 1 to 30 mm were investigated. By taking into account the simultaneous effect of thickness and crack length, a relationship for the shape factor (F) of the ECSD(UC) was presented
