چکیده انگلیسی
Using microindentation technique, localized residual stresses were created in 45S5 bioglass. The indentation-induced residual stresses increased with increasing the indentation load for the same distance to the indent center; and the magnitude of average local residual stress decreased with the increase in the distance to the indent center. The stresses-assisted dissolution of the 45S5 bioglass was demonstrated by studying the growth behavior of radial cracks in phosphate buffer solution. A linear relation between the indentation load and the ratio of the change in crack length to the square root of time was established, which was supported by experimental results.
