A versatile model that can be used for rubber polymer and biological tissues.
Ogden rubber material model.
The ogden material model is a hyperelastic material model used to describe the non linear stress strain behaviour of complex materials such as rubbers and biological tissue.
The model was developed by raymond ogden in 1972.
The ogden material model is a hyperelastic material model used to describe the non linear stress strain behaviour of complex materials such as rubbers polymers and biological tissue.
For many materials linear elastic models do not accurately describe the observed material behaviour.
The ogden model is a very general hyperelasticity model with a helmholtz free energy per reference volume that is expressed in terms of the applied principal stretches.
The ogden model has been successfully applied to the analysis of o rings seals and other industrial products.
A 3 term ogden material model can describe deformations for strains up to 600.
The helmholtz free energy for the ogden model can be written in different ways.
Ogden hyper elastic can be used to model rubber like materials undergoing large deformations.
One common compressible representation 27 is given in equation 5 117.
