The goals of our study were to calculate the subcritical crack growth (SCG) parameters of two veneering ceramics stored in water or Streptococcus mutans (S. mutans) biofilm and remineralizing medium, with indentation flaws. ...

Fracture tests in sour solution of an API X65 steel for J-R curves determination were performed at different displacement rates. The results indicated a strong dependence of J-R curves on the displacement rate. At low ...

Recovery of bioactive compounds from wastes is gaining interest because they could add value  to by-products arising from, for example, the oil extraction processes. In this work, green solvent extraction (water/ethanol ...

Objectives. Evaluate the flexural strength (sigma) and subcritical crack growth (SCG) under cyclic loading of glass-infiltrated alumina-based (IA, In-Ceram Alumina) and zirconia-reinforced (IZ, In-Ceram Zirconia) ceramics, ...
