A method for solving free torsion problem of thin-walled prismatic rods with
闭口薄壁杆件自由扭转问题的网络理论解法

A method for solving torsion of thin-walled prismatic rods with complex cross-section was presented. Based on the Prandtl's stress function solution, this method draws on the network theory approach in electrical circuit analysis via electrical analogy. The method is applicable for engineering problems of torsion of thin-walled rods with complex cross-section. It is also of pedagogic significance. Above-mentioned method will broaden students' horizon and enable them to gain more knowledge of interdisciplinary interaction.
