The numerical methods of the structural design optimization with transient response constraints have been studied in the paper. The new methods of the response analysis and sensitivity analysis for the transient dynamics and the heat conduction constraints with the precise time integration have been proposed. Particularly, an efficient method of sensitivity analysis for nonlinear transient heat conduction is given. The design optimization and finite element analysis for general structures with size and shape variables and multi-type constraints are implemented in the application software JIFEX. Numerical examples have illustrated the effectiveness of the methods presented in the paper and the facility of JIFEX software.
