Analysis on Large-scale Forging Internal Cracks Based on Fracture Mechanics
The large forgings which had over standard and non-over standard cracks by non destructive test were scrapped in subsequent machining technology,so the tolerable limit damage analysis based on stress intensity factor was adopted in the large-scale forging production process.The fracture evaluation to the large forging with cracks can reduce undue economic loss and ensure the safe and the reliability of products in the follow-up production.
