Abstract

This study was conducted in order to know the internal application of the critical strain graph. To evaluate critical strain graph, we carried out an uniaxial compression test with some of internal rocks: sandstone, shale, weathered granite, and pink granitic. Based on the uniaxial compression test, we deduced relations among critical strain, failure strain, uniaxial compression strength and modulus of elasticity. As a result, the study has found out the rocks, which have been tested, can be possibly evaluated by critical strain graph.
