Title: Crack Growth Resistance of Fiber-Reinforced Concrete Under Drop-Weight Impact Loading
Author(s): V. Bindiganavile and N. Banthia
Publication: Special Publication

Keywords: concrete; crack growth curves; fiber; fracture toughness; impact
Abstract:Dynamic fracture studies on fiber reinforced cement-based composites were conducted. Contoured double-cantilevered beam specimens were subjected to one rate of quasi-static loading and three rates of impact loading by using a fully instrumented drop weight impact machine. Steel and polypropylene fibers at two dosage rates were investigated, and an analytical scheme was developed to provide the inertial correction to measured loads and obtain crack growth resistance curves (KR Curves) under static and impact loading. KR-Curves were observed to be highly stress-rate sensitive. Comparison between steel and polypropylene fibers indicated a superior performance of the steel fiber under quasi-static loading, but under impact loading, the polypropylene fiber appears to come up to the level of steel fiber.
