A study on stress-strain behaviour of granite and sandstone using closed-circuit servo-controlled testing machine

The objective of this study is to adopt a fundamental approach towards understanding the behaviour of granite and sandstone under uniaxial compression. The study is based on the complete stress-strain curve that represents the rock deformation under loading at a constant strain rate. Indeed, the com...

Civil engineering (General) The objective of this study is to adopt a fundamental approach towards understanding the behaviour of granite and sandstone under uniaxial compression. The study is based on the complete stress-strain curve that represents the rock deformation under loading at a constant strain rate. Indeed, the complete stress-strain curve covers the behaviour of rock both at pre- and post-peak failure phases.
