The Finite element alternating method is applied to obtain the stress intensity factors of collinear multiple cracks in a thin isotropic plate subjected to bending moment. The necessary analytical solutions are obtained by using the complex stress function method given by Muskhelishvili and Savin. In order to verify the efficiency of the proposed method, several example problems are solved and compared with the published results.
- Bending moment
- Complex stress function
- Finite element alternating method
- Stress intensity factor
