MATHEMATICAL ANALYSIS OF THE LAMINATED ELASTOMERIC BEARING

Abstract

The purpose of this study was the establishment of analytical design procedures for laminated elastomeric bearings. This was approached with the application of the linear mathematical theory of elasticity and later with nonlinear large-deformation elasticity theory. The linear theory yielded analytical approximations that are close to exact solutions and which are easily applied and evaluated. This analysis of one typical lamination yields the distribution of stress and deformation in the elastomer between 'rigid' metal lamina. However, the limits of the linear elasticity theory are exceeded for greater than small bearing loads, indicating the need for the application of the more comprehensive large-deformation elasticity theory. The large-deformation theory was stated and the equilibrium equations were derived, but the solution of these equations was not carried out.
