The design method of rubber-metallic expansion joint

Abstract

Abstract The paper present the method of designing a rubber expansion joints, intended for operation in the pressure class 25 bar. During the design used a numerical analysis,which based on the finite element method (FEM). The results from experimental test were used to correctly modeled the rubber or polyamide reinforcement. Basis on the obtained results, the hyperelastic model of the rubber was prepared, then the design of the rubber expansion joint was tested in different load case, i.e tensile or compressive deflection and pressurization.
