Example code for large displacement in elastic deformation equation

Asked by Sebastian Langer

Hi,

I would like to model elastic deformation where the displacements are potentially 2 to 3 times larger than the element size.

Is there an example code or publication? Has this been done before with escript?

Thanks! Sebastian

In principle, this has been done using mesh updates for instance in https://doi.org/10.1002/nag.2908 .
Obviously, this is limited to cases of smaller distortion.
You also may want to take a look at https://doi.org/10.1007/s00024-008-0327-7 which is rate-based and uses Lagrangian finite strain tensor. One could try to use the sympy interface now to calculate the S tensor.
