A Review of Constitutive Models for Rubber-Like Materials

Abstract

<b>Problem statement:</b> This study reviewed the needs of different constitutive models for rubber like material undergone large elastic deformation. The constitutive models are widely used in Finite Element Analysis (FEA) packages for rubber components. Most of the starting point for modeling of various kinds of elastomer is a strain energy function. In order to define the hyperelastic material behavior, stress-strain response is required to determine material parameters in the strain energy potential and also proper selection of rubber elastic material model is the first attention. <b>Conclusion:</b> This review provided a sound basis decision to engineers and manufactures to choose the right model from several constitutive models based on strain energy potential for incompressible and isotropic materials

“…Many constitutive models can be used to define the hyperelastic material behaviour and determine the strain energy function such as the Mooney-Rivlin model, neoHookean model and Ogden model, etc. [32][33][34]. Analysis, in this work, was performed using the second-order Ogden model to describe the mechanical behaviour of PDMS.…”

“…In according with [4], rubber can be defined by a stored energy function as hyperelastic material. Conventional hyperelastic material models such as Ogden model works very well for silicone rubber.…”

Numerical analysis and experimental verification of elastomer bending process with different material models

“…Scientific literatures show different ways to obtain general material models [5] and many material models used in determining the elastomers characteristics [1][2][3][6][7][8][9][10]. The study was done in terms of designing in engineering practice, therefore models implemented in FEM software were used: Neo-Hookean, Mooney (2) (with two constant), Mooney (3) (with three constants), Signorini, Yeoh, Ogden (with the number of components equals N = 1, 2 and 3), ArrudaBoyce, Gent and Marlow [6][7][8][9][10].…”

Scientific literature reported that approximately 60% of all aviation sheet metal parts are shaped using rubber tools [1,2]. Elastomers and natural rubber are applied as a group of tools used in various technological forming operations including bending, punching, stamping, etc.…”
