Improved resonance reliability and global sensitivity analysis of multi-span pipes conveying fluid based on active learning Kriging model

In this paper, the improved resonance reliability and global sensitivity analysis of multi-span pipes conveying fluid is proposed via active learning Kriging model. The natural frequency of multi-span functionally graded materials pipes conveying fluid is calculated using the dynamic stiffness method. A new improved resonance performance function is proposed which is suitable for both broadband and multi-frequency resonance failure. This paper...
