Investigation of fracture of inhomogeneous cast iron specimens

E. Stupak


The proposed J-integral calculation technique in the piece-wise linear fatigue crack front has been used investigating SIF in the inhomogeneous cast iron speci-mens with defect and graphite voids.

The influence of crack length and front, size and position of voids on SIF have been investigated and the increase of SIF by 15% has been obtained.

Stress-strain state analysis of inhomogeneous cast iron specimens was carried out using FE code ANSYS.
