Abstract:Despite their high strength-to-weight ratio, short fiber reinforced composites, due to their intrinsically heterogeneous microstructures, exhibit complex mechanical behavior, especially relating to failure. This study explores the dependency of micro-void nucleation on microstructural defects by ranking contributions of competing microstructural metrics, as identified through in-situ X-ray microtomography. Using a Gaussian process framework, six metrics were explored which capture the properties of the closest… 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.
