| Abstract: | Based on Koiter's upper bound shakedown theorem, the cynulation of plastic deformation in cylindrical thin shells subjected to cyclically moving thermal load and stationary mechanical loads is analyticaly discussed. The positions, shapes, sizes and shakedown limit load expressions are given. Some examples are calculated. The results show that the theoretical loads are quite close to those calculated with FEM. |
