Die stresses considering shrink fit, 2D

Elastoplastic finite element prediction of plastic flow problem can also be conducted considering elastic deformation of dies due to not only mechanical load but also shrink fit. This example is one of typical applications to axi-symmetric forging process. All the solutions of dies were obtained at the same time with plastic deformation of the material.
