Structural Finite-Element Analysis with New Interface Model
Publication: Journal of Engineering Mechanics
Volume 123, Issue 3
Abstract
The constitutive model of interface behavior in quasi-brittle materials developed by the writers is incorporated with the finite-element method. The procedure and problems about the formulation of interface element are analyzed in detail. The three-term recursive equation is modified to ensure the convergency of the dynamic relaxation process in the softening stage of the present study. A simple way of realizing the prescribed displacement constraint conditions is suggested for the dynamic relaxation iterative process. A finite-element code, SANIM (Structural Analysis with a New Interface Model), which can be used in quasi-brittle material structure analysis for different purposes, is developed. Numerical results were compared favorably with the experimental results of a rock salt specimen under direct tension.
