Finite Element for Rock Joints and Interfaces
TLDR
In this paper, the authors presented a method for dynamic stress analysis of saturated soil structures subjected to earthquake loading, where the soil was idealized as a fluid saturated porous solid and the coupled equations of motion of the finite element discretized system were solved by a step-by-step integration scheme to determine the motion of constituent materials along with the intergranular stresses and the pore pressure.Abstract:
The objective of this paper is to present a method for dynamic stress analysis of saturated soil structures subjected to earthquake loading. The soil is idealized as a fluid saturated porous solid. The coupled equations of motion of the finite element discretized system are solved by a step-by-step integration scheme to determine the motion of the constituent materials along with the intergranular stresses and the pore pressure. Finally, some results of an illustrative example of an earth dam-reservoir system are presented and analyzed.read more

Constitutive models for rock discontinuities with dilatancy and surface degradation
TL;DR: In this paper, a physically motivated constitutive law for the behaviour of geologic discontinuities with dilatancy and contact surface degradation (damage) is presented, which is applicable to a large class of contact-friction problems.
