Dear Abdelrahman, To add to some further details to what Konrad has already provided: - the step-44 tutorial <https://www.dealii.org/current/doxygen/deal.II/step_44.html> implements one of many incompressible elasticity formulations. There is also the Quasi-Static Finite-Strain Quasi-incompressible Visco-elasticity <https://www.dealii.org/current/doxygen/deal.II/code_gallery_Quasi_static_Finite_strain_Quasi_incompressible_ViscoElasticity.html> code gallery example that implements a linear viscoelastic model in combination with near-incompressible material behaviour. - the Quasi-Static Finite-Strain Compressible Elasticity <https://www.dealii.org/current/doxygen/deal.II/code_gallery_Quasi_static_Finite_strain_Compressible_Elasticity.html> code gallery example implements a more traditional finite strain elasticity formulation, which could also be a basis for extension to other incompressibility formulations. - the (new) step-71 tutorial <https://www.dealii.org/current/doxygen/deal.II/step_71.html> introduces some useful techniques that can be applied to modelling complex constitutive laws. As a part of this tutorial, a magneto-viscoelastic constitutive law is implemented and verified.
If you have a look at the “Applications” tab on the top of the home page (https://www.dealii.org/ <https://www.dealii.org/>), then you can see some of the libraries that are built on top of deal.II — some of these include some interesting and challenging constitutive laws. You can also look to those for inspiration on how to implement your constitutive laws within a finite element framework. Best, Jean-Paul > On 19.
