A proposed specimen for KIIC testing
Source abstract
Abstract
Unlike mode I, mode II fracture toughness (KIIC) testing is still some way from standardization. In the present study, a specimen is proposed for KIIC testing. The specimen is an adaptation of Richard's (1981) specimen, with the exception that the ligament is extended. Based on numerical analysis, the suitability of the proposed specimen has been assessed by comparing it against the two commonly-used mode II specimens of Banks-Sills and Arcan (1986), and Richard (1981), respectively. In comparison, the proposed specimen has been found to be more compact, and to have a significantly lower intensity of normal stress ahead of the crack tip. As a result, it may be inferred that the proposed specimen would be more suitable for KIIC testing. The modes I and II K-calibration formulae of the proposed specimen have also been deduced.
