Determination of fracture toughness of human enamel by nanoindentation based on energy release method

Original language description

Enamel is a brittle material. The main property showing its fracture resistance is fracture toughness. The aim of this study is to determine parameters necessary to estimate fracture toughness by the nanoindentation method. The method of fracture toughness evaluation based on dissipation of energy is described. In the first section of study, changes in values of hardness (HIT) and reduced modulus (Er) are observed with regard to crack initiation and growth. The downward trend of HIT was found with the increasing peak load. The next section is focused on the loading rate impact on crack formation. The results supported the assumption that higher rates of loading induce greater crack formation.
