AbstraktAbstract
A fracture toughness test measures the resistance of a material to crack extension. Such a test may yield either a single value of fracture toughness or a resistance curve. Measurement of the resistance curve requires knowledge about crack initiation and its growing during loading. Concurrently knowledge about shape and scale of the damage zone is advantageous. X-ray Dynamic Defectoscopy was developed for these purposes. This method is suitable for detailed measurement of the crack growth, opening and branching. Simultaneously employed optical Digital Image Correlation method served for full field measurement of the displacement in the relatively large area surrounding crack tip.
