Finite Element Analysis on the Stress Intensity Factor in SENT Specimen of Clam Steel

Abstract

The Ansys finite element software is used to calculate the crack opening displacement and Stress intensity factor (SIF) for Single-edged notched tension (SENT) specimen of Clam steel under the tension of 1000N. During the simulation, the crack opening positions for five groups and the different crack length were set up. The numerical simulation shows that the Model I intensity factor (KI) is larger one order than the Model II intensity factor (KII), the values of the SIF is not related to the crack opening displacement. The SIF is more influenced by the crack opening position and the crack size.
