Silicone Rubber Material Model

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.

Silicone rubber material model. Description of the behaviour of rubber like materials in engineering applications. Choose from our selection of silicone rubber including over 4 300 products in a wide range of styles and sizes. For this reason epdm material is an excellent medium for outdoor uses. To reduced requirements for material testing14.

For many materials linear elastic models do not accurately describe the observed material behaviour. 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. The calibrated material model is the polyumod bergstrom boyce bb model.

Here is a calibrated material model for a generic silicone rubber tested at room temperature. Create a hyperelastic material named rubber. Rubber edging can help to protect exposed edges of glass wood and metal from wind water and dust. Silicone rubber silicon rubber is a superior choice for applications that deal with extreme temperatures.

It achieves an ideal balance to create an all purpose weather resistant rubber. Material model for silicone rubber. 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.

Rubber material is available in a variety of forms for industrial manufacturing and protective applications. To use this material model you will need to first install the mcalibration software and then export the model to your favorite fe software. Neoprene rubber neoprene rubber is a multipurpose elastomer that provides oil and ozone resistance for demanding applications. Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.

In stock and ready to ship. Round rubber grommets can help to prevent abrasion damage on wires and other objects inserted through holes in hard materials. Thus select polynomial from the strain energy potential list in the material editor. Viton is a go to rubber material for applications that require fuel and oil resistance.
