Fracture Test and Numerical Analysis of Structural Steel Notched Plates Based on Generalized Strength Model

Abstract:

Article Preview

To study rupture mechanism of structural steel, fracture experiments were tested on 12 notched plates with different thickness. The results of experiments indicated that the first crack initiated at the notched edge and expanded rapidly along the width of the plates after running through the thickness. Finally, the specimens fractured at the critical section, the fracture ductility decreased with the thickness. By numerically simulating the fracture stress field of the notched plates at initial cracking based on generalized yield model, the applicability and accuracy of the suggested fracture criterion were comparatively verified.
