Reliability-Based Optimization Design of Variable Cross-Section Component

Variable cross-section components are widely used in engineering practice. It is clear that reliability-based optimization design of variable cross-section component is important for engineering design. This variable section widget for reliability and the perturbation design, we propose a perturbation method of the reliability design about the variable cross-section components. We may rapidly obtain the variable cross-section component's reliability information accurately, in basic random variable probability characteristic certain situation. We propose a method with practicality for the relevant reliability design.
