Application the Thermomechanical Damage Modeling Approach with Generalized Non-linear Strength Theory

摘要

This paper builds the formulations of thermomechanical damage modeling approach with generalized non-linear strength theory. The bulk and the likely damage behavior can be described. The independent kinematic internal variables are introduced to describe the damage behavior and structural rearrangement of the Geo-granules for bulk deformation. The accordingly generalized stress can be deduced by combining the given thermodynamical energy functions. A systematic constitutive presentation is presented through the thermodynamical damage framework with generalized non-linear strength theory. The theory is based on previous work by Houlsby et al., and extends to the multi-mechanisms (Guo & Zhao et al.) description for geomaterial.
