Transferability of fracture mechanical data from sub-sized three point bend specimens
Original language description
The contribution deals with FEA of stress state in sub-sized pre-cracked three-point bend specimen with dimensions 3427 mm3. In the experimental part the true stress-true strain curve was obtained from tensile test from Eurofer´97 steel. Next, the staticthree point bend tests with different crack lengths were carried out on plain and side-grooved specimens. The tests were simulated using ABAQUS 6.10. For comparison, models of pre-cracked standard and Charpy specimen were also created. The stress levelbelow the crack tip for both KLST and Charpy specimen decrease more extensively than for standard specimen indicating the constraint loss. The decrease of the stress level and thus constraint loss is the highest just for the smallest specimen. The different crack lengths have no influence on the stress level at the crack tip. The side grooving enabled to maintain the stress level at the crack tip along the thickness but does not have effect on the maximum value of the stress.
