An Experimental Investigation of the Stress Approach

Source

Many investigations have identified geometry dependence of J_c at initiation of cleavage fracture and J_i at initiation of fibrous tearing. This geometry dependence is predictable from elastic-plastic finite element analyses, which show that the crack tip stress-strain distribution is not always uniquely defined by J. This paper investigates the ability of the elastic T stress to explain experimentally observed trends in J_c with changes in specimen geometry. Data on mild steel three-point bend and center-cracked tension specimens are presented.
