The Constitutive Model for Isotropic Damage of Geomaterial
A constitutive model for isotropic damage of geomaterial is put forward, and its numerical computation procedure is given also. The calculated results for a simple example could highlight our understanding about the mechanism of geomaterial damage, and several useful conclusions can be drawn: The series assumption can not be used to synthesis mode of stress and strain for complexus theory of geomaterials damage; strictly speaking, the parallel assumption can not be used to that of geomaterials damage also; the complexus stress-strain behavior like that of ideal natural geomaterial under small stress, and like that of reconstituted soil under large stress.
