Stress intensity factors of elliptical cracks at the weld toe

The paper takes into account the assessment of the stress intensity factor (SIF) of defects similar to elliptical cracks located at the weld toe. By assuming a second order approximation of the Oore-Burns equations the SIF has been evaluated with simplified equations. The analytical results are compared with those evaluated by means of the finite elements method. As an example, the SIF is calculated for a defect located in the neighborhood of the weld toe of full penetration cruciform joints under mode I loading.

Automated summary

This paper evaluates the stress intensity factor (SIF) of elliptical cracks located at the weld toe by using simplified equations and compares the results with those obtained from the finite elements method. As an example, the SIF of a defect near the weld toe of full penetration cruciform joints under mode I loading is calculated.
