Abstract
The fracture and inelastic behavior of A-W glass-ceramics, phosphate glasses, silicate glasses, and borate glasses were determined in simulated body fluid (SBF), kerosene, and water. By using the stable crack growth technique, an inelastic behavior was observed on the diagram of load versus load-point displacement. From these studies, it was suggested that the inelastic behavior of bioactive glass-ceramics was produced by the plastic deformation of glassy phase on the grain boundary.
