Basic Mechanics of De Bange Obturator Split Ring Prestressing

Abstract

An analysis is presented to show the relationship between the maximum obtainable residual shear force in a split ring perform and the prestressing parameters (included angle between fixture grips and total angle of twist). Also included is an analysis of the section depth of the ring that is required to provide sufficient material for the finishing machining operation. Application of the formulas derived would require the quantification of certain parameters by either experimental or numerical methods.
