Experimental data on the standard Charpy notched impact strength (CNIS) for a large sampling of particulate‐filled and rubber‐modified polypropylenes were analyzed. To determine the significance of the CNIS for material selection and design, CNIS data were compared with fracture toughness measurements expressed as the critical strain energy release rate G′c, measured under impact loading. A scale factor representing the state of stress at the crack tip was calculated, assuming small scale yielding, C…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific 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 researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
