... the detailed information of the inside fracture and damage of SRM. Based on the CT identification and the damage mechanics theory, a damage variable was proposed and the isotropic damage property of SRM amid a complete compressive stress-strain response was analyzed. This paper provides direct experimental...

... phase volcanic breccias were also studied. Creep damage variable and related evolution equation in accelerated creep were proposed. Based on the relation of damage variable associated with lateral creep strain, the correlativity between axial permeability coefficient and lateral damage-induced strain...

... of damage parameter with those stress- strain relation. 3 EXPASION DAMAGE MODEL 3.1 Fundamental concept In damage mechanics (Lemaitre 1992), the change in mechanical behavior due to the growth of damage (cracks) in material is dealt with. This behavior is expressed by means of damage variable D...
