Abstract:Silicone rubber samples with gradually changing pore sizes within the range of 70-610 μm are produced using an improved spacer method. The samples are scanned using an X-ray computed tomography to evaluate their graded structure as compared to uniform rubber. A compressive test reveals that graded porous silicone rubber has characteristic stress-strain curves whose slope changes within a specific strain range depending on the porous structure. Analysis results of local strain based on a digital image correlati… Show more
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.
