Engineering Fracture Mechanics 96 : 209-225. ScholarBank@NUS Repository. https://doi.org/10.1016/j.engfracmech.2012.07.022 | Abstract: | This study investigated experimentally the fracture resistance for aluminum alloy 5083-H112 specimens over the complete range of mixed-mode I and II loadings. The determination of the amount of crack extension utilized two approaches, the compliance method for opening-type specimens and the striation markings for shear-type specimens. The post-test examination on the fracture surfaces validated these two methods. The increase in mode II loading elevates the fracture resistance curve for mode I dominant specimens, but reduces subsequently the fracture resistance as the mode-mixity transforms the fracture mode from the opening-type to the shear-type. © 2012 Elsevier Ltd. | Source Title: | Engineering Fracture Mechanics | URI: | http://scholarbank.nus.edu.sg/handle/10635/90980 | ISSN: | 00137944 | DOI: | 10.1016/j.engfracmech.2012.07.022 |
