Hyperelastic rubber
WebThis type of material behavior is called hyperelasticity. The deformation of hyperelastic materials, such as rubber, remains elastic up to large strain values (often well over 100%). ABAQUS/Explicit makes the following assumptions when modeling a hyperelastic material: The material behavior is elastic. The material behavior is isotropic. 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 observ…

Web10 apr. 2024 · The analysis of propagating an initially harmonic acoustic pulse in a semi-infinite hyperelastic rod obeying the Yeoh strain energy potential reveals attenuation with distance of the wave amplitudes caused by the elastic energy dissipation due to forming and propagation of the shock wave fronts and heat production. The observed attenuation of … Web7 okt. 2024 · This approach is applied to determine the hyperelastic material parameters of rubber specimens with a cruciform shape [34,50,51,52]. Similar to the previously described approaches, the selection of the initial parameters and optimization techniques directly affects the quality of the prediction in this approach.
Web1 dec. 2008 · Hyperelastic constitutive models Experimental data obtained from tests are useful to calibrate constitutive models in order to accurately reproduce mechanical behaviour of the material in FEM simulations. Rubber-like materials exhibit very large strains, with strongly non-linear stress–strain behaviour. Webrubber sheets at impact rates of loading. Results from the uniaxial tension tests indicated that although the rubber became stiffer with increasing strain rate, the stress-extension ratio curves remained virtually the same above 280 s-1. Above this critical strain rate, strength, fracture strain and toughness decreased with increasing strain rate.
WebHyperelastic materials are described in terms of a “strain energy potential,” , which defines the strain energy stored in the material per unit of reference volume (volume in the initial configuration) as a function of the strain at that point in the material.There are several forms of strain energy potentials available in ABAQUS to model approximately incompressible … Web11 nov. 2024 · Hyperelastic Mooney-Rivlin Model : Determination and Physical Interpretation of Material Constants Jan 2016 43-46 N Kumar V V Rao Kumar, N., Rao, V.V.
