The shear strength of rock and rock joints
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1976Abstract Rock joints exhibit a wide spectrum of shear strength under the low effective normal stress levels operating in most rock engineering problems. This is due to the Strong influence of surface roughness and variable rock strength. Conversely, under the high effective normal stress levels of interest to tectonophysicists the shear strength ...

Rock joints: Theory, constitutive equations
1995Publisher Summary This chapter describes constitutive equations for rock joints that include phenomena, such as friction, dilatancy, damage of surface roughness, and the ability to treat arbitrary small deformation histories. The major features of the constitutive theories described in this chapter are that they are based on specific microstructural ...

This report discusses several constitutive models for joint behavior with emphasis upon the experimental data which motivates them. Particular emphasis is placed upon data available for granite. The LDEC joint model is presented in detail and LDEC simulations using this model are compared against data from constant normal stiffness and constant normal ...

Engineers from TU Delft and doctors from Leiden are joining forces to make loose-fitting artificial joints a thing of the past. They are at the forefront in terms of minimally invasive interventions, which make cutting open patients unnecessary. “Nobody else is doing this yet.”

Stability calculations in jointed rock mass: Dissertation
1989An isoparametric two dimensional joint element with independent non linear behaviour models for normal and shear stress has been used to study different failure criteria and the accuracy of calculations.Testing of the behaviour models indicated similar results obtained by other researchers with different finite element codes.JRTEMP is the first finite ...
