Frictional Characteristics of Cracks and Failure of Brittle Materials under Dynamic Compression
Abstract
A newly developed specimen has been used to investigate the compressive failure due to the presence of flaws in brittle materials. Experiments were conducted under both static and dynamic loading conditions to delineate the role of friction on sliding induced crack initiation. Specimens with different coefficients of friction and crack inclination were prepared and a systematic understanding of crack initiation under compressive loading has emerged. The onset of crack growth is dynamic even under quasi-static loading conditions and the crack initiation is suppressed by presence even small amounts of lateral confinement.
