ABSTRACT
This paper describes both analytical and experimental studies to determine the effect of high shear strain on the critical loads of a set of 5 inch and 10 inch square elastomeric bearings with shape factors ranging from 1.7 to 10.0. The results from ADINA finite element solutions are described and compared against experimental tests. Demonstration of significant axial load capacity at high shear strain is presented, and the effect of end (boundary) conditions is illustrated. It is proposed that three regions be defined on the critical load-shear displacement plot which identify stable, unstable and transition conditions respectively.(AU)
