Numerical analysis of an elastomeric bearing pad by hyperelastic models

Abstract Elastomeric bearing pads are responsible for transfering loads at the junction between beams and columns of bridges and viaducts, providing restrict freedom of movement in the superstructure. The elastomeric material of bearing pads is a synthetic rubber reinforced with carbon black particl...
