The idea of using a thin solid element, called a thin-layer element, in soil-structure interaction and rock joints is proposed. A special constitutive model is used and various deformation modes such as no slip, slip, debonding and rebonding are incorporated. The shear stiffness is found from special laboratory tests and the normal stiffness is assumed to be composed of participation of the thin-layer element and the adjoining solid elements. A parametric study shows that the thickness of the thin-layer element can be such that the ratio of thickness to (mean) dimension of the adjacent element is in the range of 0.01 to 0.1. A number of simple and practical problems are solved to illustrate the success of the thin-layer element for soil-structure interaction problems.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.

A simple contact–friction interface element with applications to buried culverts
TL;DR: In this article, a simple friction contact interface element is introduced which simulates frictional slippage, separation, and re-bonding of two bodies initially mating at a common interface and subsequently deforming with an arbitrary static loading schedule.

Finite Element Analysis of Contact Problems
TL;DR: In this paper, a finite element procedure for modeling the interaction of contacting bodies is developed and illustrated, which is capable of accounting for both slippage and separation of the mating surfaces.
Attenuation of stresses for buried cylinders
J Q Burns,R M Richard +1 more
TL;DR: In this article, an analysis for the interaction of an elastic cylindrical shell embedded in an elastic medium which is loaded by a surface overpressure is presented, and the analysis is made through the use of extensional shell theory for the shell and Michell's formulation of Airy's stress function for the medium.
