| 摘 要： | Giving a nonisotropic plasticity problem on a Sobolev Space, the author tries to relax it to a new problem whioh is posed on a subset of BD (Ω). It is proved that this relaxation does not change the equilibrium energy and that the solutions exist in such settings under not too restricted conditions.

| Abstract: | Giving a nonisotropic plasticity problem, on a Sobolev Space, the author tries to relax it to a new problem which is posed on a subset of BD($\\Omega \]$). It is proved that this relaxation does not change the equilibrium energy and that the solutions exist in snch settings under not too restricted conditions. |
