Abstract
Problem statement: 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. Conclusion: 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.
Highlights
IntroductionThe term elastomer is the combination of elastic and polymer and is often used interchangeably with the rubber (Smith, 1993)
Rubber material usually has long chain molecules recognized as polymers
Rubber component as an engineering material has been used in many industries such as automotive and in a wide range of applications consist of engine mountings, tires, vibration isolators, medical devices and structural bearings
Summary
The term elastomer is the combination of elastic and polymer and is often used interchangeably with the rubber (Smith, 1993). Elastomers have special physical properties (flexibility, extensibility, resiliency and durability), which are unmatched by other types of materials (Coran, 2006), it still presents behavior in common with other material (Abraham et al, 2005). This notable characteristics change with diverse variable including fatigue, light, heat, oxygen and ozone, during passing of time (Nagdi, 1993).
