Two aspects of the work were examined. The first was concerned with the finite element implementation of the variational inequalities approach to treat the general contact problem. Quadratic programming and Lagrange multipliers were used to identify the candidate contact surface and to solve the resulting nonlinear equations. The solution strategy was based upon the use of a two-step algorithm, which guaranteed the accurate imposition of the active kinematic contact constraints and evaluated the contact forces without the use of special contact elements. The second aspect of work was concerned with the application of an enhanced image-processing technique to obtain the stress field resulting from an automated photoelastic rig. A hybrid method was also employed to determine the contact forces between the multiple discs. The results revealed close agreement between experimentally determined contact values and finite element predictions. Furthermore, they indicated load redistribution and load sharing as well as the influence of interfacial friction.Keywords:ContactMultiple DiscsVariational InequalityFinite ElementPhotoelasticityFriction FiguresReferencesRelatedDetailsCited By 1Finite element linear and nonlinear, static and dynamic analysis of structural elements, an addendumJaroslav Mackerle1 Aug 2002 | Engineering Computations, Vol. 19, No. 5 Recommended Vol. 02, No. 01 Metrics History KeywordsContactMultiple DiscsVariational InequalityFinite ElementPhotoelasticityFrictionPDF download
