Application of structural optimization and nonlinear finite element technique to nonlinear multi-component structural system (assembly) is studied for the sake of the obturator of the breech mechanism of an automated mortar. The method and technology for optimizing nonlinear multi-component structural system with contact is mainly researched in this thesis.
The main research work is composed of the followings: 1) A new method for optimal design of nonlinear multi-component structural ...
