FEM Analysis and Verification of Stress Intensity Factor of Dugdale Model in Silicon Steel Plate under Biaxial Tensile Load
A plate containing a central crack and subjected to biaxial stresses has been studied by a finite element method using ANSYS. The stress intensity factor was calculated using displacement extrapolation method and Dugdal model. From the results, it was found that the stress intensity factors increased with the increasing load ratio. There was good agreement between experimental and theoretical results.
