Scaled toughness
WebSome toughness scaling models (TSMs) were proposed to transfer the tested value to fracture toughness under small-scale yielding. Combined with the tested data by SENB specimens with different crack sizes and CT specimens with different thicknesses, the scaled fracture toughness is investigated on the global and local approaches to fracture. Web2 TOUGHNESS SCALING MODELS 2.1 Global Approach to J-Q Theory The variations in fracture toughness resulting from the loss of constraint due to crack length are usually scaled by a 2D small-...
