Brittleness Definition & Meaning Dictionary.com
WebIn materials science, brittleness is understood as the lack of ductility. For engineers, ... High ductility in these applications helps prevent brittle fracture. Brittle Materials. Brittle materials, when subjected to stress, break with little elastic deformation and without significant plastic deformation. Web13 de jan. de 2024 · The brittleness index (BI) is a key parameter used to identify the desirable fracturing intervals of shale gas reservoirs. Its correlation with fracability is still controversial. There have been a variety of methods proposed that can estimate BI.
