Silicone Rubber Material Model

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.

Silicone rubber material model.

Rubber edging can help to protect exposed edges of glass wood and metal from wind water and dust. To reduced requirements for material testing14. Neoprene rubber neoprene rubber is a multipurpose elastomer that provides oil and ozone resistance for demanding applications. Here is a calibrated material model for a generic silicone rubber tested at room temperature.

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. For many materials linear elastic models do not accurately describe the observed material behaviour. To use this material model you will need to first install the mcalibration software and then export the model to your favorite fe software. Thus select polynomial from the strain energy potential list in the material editor.

Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost. Ogden model proposed in 1972 by ogden15 16 this is also a phenomenological model and is based on principal stretches. 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.

Viton is a go to rubber material for applications that require fuel and oil resistance. 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. The calibrated material model is the polyumod bergstrom boyce bb model.

In this example a first order polynomial strain energy function is used to model the rubber 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. 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. Material model for silicone rubber.

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. Enter the test data given above using the test data menu items in the material editor. Round rubber grommets can help to prevent abrasion damage on wires and other objects inserted through holes in hard materials. Description of the behaviour of rubber like materials in engineering applications.
