Abstract
Austempered ductile iron (ADI) represents wide segments of engineering applications. In the present investigation, Single edge notch bending (SENB) samples austempered at 300 °C for 120 minutes duration were subjected to three-point bending test to evaluate the plane strain fracture toughness (KIC) of ADI. The presence of crack in mechanical components is due to several reasons like casting, forging, rolling, and machining defects. The detailed fracture assessment of ADI is analysed considering hypothetical crack-like defects. Stress Intensity factor (KI) at the vicinity of the crack tip was obtained for centre crack and edge crack considering different crack lengths under Mode-I loading utilizing ANSYS as a software. The component failure occurs when the stress intensity factor exceeds the fracture toughness of the material. The significance of fracture toughness of ADI is highlighted by comparing the same with the stress intensity factor at the vicinity of the crack tip.
