Abstract:This paper suggests a simple loading configuration for conducting the SCB (semi‐circular bend) tests on brittle materials to produce mixed mode I/III loadings. In the suggested test setup, the SCB specimen containing an inclined crack is loaded using a conventional three‐point bending fixture, but the bottom supports touches nearly half of the specimen thickness rather than the entire thickness. It is found that various mixed mode I/III loadings can be provided by rotating the crack, and especially the SCB spe… Show more
According to the engineering and experiment demands, different fracture testing approaches are proposed and modified, including mixed-mode I/II, ture mode-II, and mixed-mode I/III, the detailed introductions are as follows.

Shale reservoirs are characterized by both ultralow porosity and permeability, the attached shale gas can be effectively extracted by hydraulic fracturing (also known as fracking) technique to optimize the energy structure.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
