The prediction of size effect on J R curve for Eurofer97 steel by simplified mechanical model
Original language description
The possibilities to derive fracture toughness from small specimens are naturally limited due to constraint requirements which are especially restrictive in toughness testing. The loss of constraint at the crack tip is more likely to occur as specimen size decreases. Application of miniature specimens in fracture toughness testing thus requires a suitable methodology or correction procedure to deal with phenomenon of the constraint loss. Schindler et al. have proposed a simplified mechanical model thatcan be used to scale up the key test characteristics from miniature specimen to the larger one. The model is applied to the miniature bending specimens to describe size effect on J R curve of the Eurofer97 steel. The examined steel exhibits quite high toughness values at upper shelf region of fracture toughness. As a result, experimentally determined J R curves of three different sizes of pre cracked bending specimens showed high values of J integral, which were significantly different e
