Experimental Study on Mechanical Deformation and Energy Evolution of Deep Coal Under Complex Stress Paths

Experimental Study on Mechanical Deformation and Energy Evolution of Deep Coal Under Complex Stress Paths

This study proposes a novel cyclic stress path with simultaneous axial and confining stress and conducts triaxial testing on raw coal over various cycle periods. The analysis of bias stress–strain curves, deformation parameters, and energy indexes elucidated the mechanical and energy evolution patte...
