Numerical Simulation of the Stress and Distortion of the Fiberglass-Reinforced Plastics Crust-Stainless Steel Liner Compound Conduit

Hongyuan FANG , Chenglei FAN , Jianguo YANG , Ming LI , Zhen LUO , Xianzhong HOU

材料科学技术（英文）

A new type of compound conduit is designed and the finite element method (FEM) is applied to analyze the mechanical performance of a typical compound conduit. The results of the numerical simulation confirm that the distributions of the strain, stress and the flexure distortion of the conduit are re...
