Silicone rubber material model.

Here is a calibrated material model for a generic silicone rubber tested at room temperature. Enter the test data given above using the test data menu items in the material editor. Ogden model proposed in 1972 by ogden15 16 this is also a phenomenological model and is based on principal stretches. In this example a first order polynomial strain energy function is used to model the rubber material.

Silicone rubber is an elastomer rubber like material composed of silicone itself a polymer containing silicon together with carbon hydrogen and oxygen silicone rubbers are widely used in industry and there are multiple formulations. Rubber material is available in a variety of forms for industrial manufacturing and protective applications. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Rubber like material constitutive modelling mullins effect continuum damage mechanics pseudo elastic model finite element method 1 introduction rubber like materials exhibit a highly nonlinear behaviour characterized by hyperelastic.

Thus select polynomial from the strain energy potential list in the material editor. Description of the behaviour of rubber like materials in engineering applications. Viton is a go to rubber material for applications that require fuel and oil resistance. To use this material model you will need to first install the mcalibration software and then export the model to your favorite fe software.

A hyperelastic or green elastic material is a type of constitutive model for ideally elastic material for which the stress strain relationship derives from a strain energy density function the hyperelastic material is a special case of a cauchy elastic material. The yeoh model is also called the reduced polynomial model and for compressible rubber can be given as i 2i i0 1 el i1 i1 i 1 w ci 3 j 1 d 7 2 6. Material model for silicone rubber. Choose from our selection of silicone rubber including over 4 300 products in a wide range of styles and sizes.

For many materials linear elastic models do not accurately describe the observed material behaviour. Epdm sheet rubber is a versatile blended sheet epdm sheet rubber is a versatile blended sheet composed of ethylene propylene diene monomer and styrene butadiene rubber. Round rubber grommets can help to prevent abrasion damage on wires and other objects inserted through holes in hard materials. The calibrated material model is the polyumod bergstrom boyce bb model.

To reduced requirements for material testing14. Silicone rubber silicon rubber is a superior choice for applications that deal with extreme temperatures. Neoprene rubber neoprene rubber is a multipurpose elastomer that provides oil and ozone resistance for demanding applications. Create a hyperelastic material named rubber.
