Regularization and existence of solutions of three-dimensional elastoplastic problems
Martin Brokate, A. M. Khludnev · Mathematical Methods in the Applied Sciences · 1998
We prove the existence of solutions to the three-dimensional elastoplastic problem with Hencky's law and Neumann boundary conditions by elliptic regularization and the penalty method, both for the case of a smooth boundary and of an interior two dimensional crack. It is shown, in particular, that the variational solution satisfies all boundary conditions. © 1998 B. G. Teubner Stuttgart–John Wiley & Sons Ltd.
