Abstract:The tensile strength of a copy paper with a center notch was measured. During the test, the loading direction coincided with the cross direction (CD) or the machine direction (MD) of the paper sheet, and the configuration and dimension of the notch were varied. The relationship between the tensile strength and notch dimension was fitted using the following four theories: uniform stress criterion (USC), point stress criterion (PSC), average stress criterion (ASC), and fracture mechanics theory (FMT).

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.
