Abstract:Strain-rate effects on the deflection/ penetration behaviors of a crack terminating perpendicular to a linear elastic bimaterial interface under dynamic tensile loadings are investigated numerically with the so-called Cohesive Crack Model and quasistatic material parameters. The competition between the deflection and the penetration is found to depend markedly on the loading rate (or the strain rate) and amplitude as well as the interfacial strength. The crack can penetrate through the interface only when the … 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.
