FINITE ELEMENT FOR ROCK JOINTS AND INTERFACES

In a discussion of this paper, comments are made regarding a point which needs clarification. The joint stiffness matrix presented by the authors for a 2-dimensional case is a 4 x 4 matrix which yields the four relative displacements of the two ends (this could be obtained from the eight displacements of the Goodman-Taylor-Brekke's model). But how are the eight displacements obtained from the joint nodes? The discussant also comments that in the finite element analysis. However, as long as the values of the normal and shear stifnesses are not well established by laboratory or field tests, or both, the usefulness of the joint element will be limited to the demonstration of solutions of problems which serve, at best, as examples of academic exercise. there is no doubt about the advantages of the joint element
