Use the Combination Finite Element Method to Solve the Crack Cylinder of the Torsion Problem

摘要

Based on Muskhelishvili's theoretical expressions of the Saint-Venant's problem, using the combination of Crack3D code and Ansys software, a new combination finite element method to calculate the Saint-Venant's torsion problem including crack is proposed. In order to illustrate its application, the numerical examples for a torsion cylinder with crack are given and the numerical results are satisfactory.
