Constitutive Model and Fracture Failure of Sandstone Damage under High Temperature–Cyclic Stress

Constitutive Model and Fracture Failure of Sandstone Damage under High Temperature–Cyclic Stress

Deformation and damage characteristics of high-temperature rocks during underground coal gasification are the fundamental mechanical problems encountered in coal-bed gasification production. In order to study the characteristics of deformation and damage processes of rocks under the joint action of...
