摘要: Fracture toughness, critical strain energy release rate and stress intensity factor were determined for lathe-cut, spherical, admixed, two atomized high-copper dental amalgams. At a loading of 0.005cm min−1 24-hour samples, the spherical amalgam had highest resistance to unstable crack propagation. 0.05cm both one-month lathe-cut One high copper amalgams showed lowest The values consistent with data obtained in single-pass wear studies.
