| Abstract: | The concept of topology optimization of truss structures with discrete variables including two kinds of variables and the relative difference quotient algorithm for discrete optimization are extended to the topology optimization of plate and shell structures composed by plate and shell elements. A mathematical model of topology optimization of plate and shell structures is established and a relative difference quotient algorithm (RDQA) is used to solve the above model. In the end, an engineering practical example of a topology optimization for a supporting beam of a special vehicle is given. |
