Abstract

A one-dimensional model for multilayered (laminated) rubber bearings is deduced from three-dimensional finite elasticity by means of the imposition of appropriate internal constraints and a suitable choice of the constitutive equation. A closed-form solution is easily obtained in the case of simple compression, so that a load-stretching relation can be established. Small deformations superimposed on finite compression are also studied, and critical compressive loads, superimposed small shear and superimposed small bending are discussed in detail. Finally, to illustrate the significance of the results, some comparisons with previous analyses and experiments are examined.
