| Abstract |
In the technological processes of manufacturing thin-walled parts for aircraft industry, the stages of shaping in the creep mode are used. Such modes make it possible to control damage by choosing a kinematic deformation scheme. An optimal control problem, which is solved by the dynamic programming method, is formulated. The implementation of the numerical optimization method has been carried out using the Marc finite element software package. To analyze deformation schemes, modeling of the panel shaping process in a reconfigurable core punch is considered. Highstrength alloys can manifest the properties of anisotropy and multimodulus behavior to tension and compression. According to the obtained results, these properties correspond to different kinematic deformation schemes. |
