Abstract:
Deformation behavior of human enamel under diametral compression is examined. Enamel is a brittle substance under tensile stress: the deformation curve can be approximated by the straight line and the sample fails as soon as the maximal stress is reached. The diametral tensile strength of human enamel is ~40 MPa, the elastic modulus is ~3.5 GPa and the total deformation is ~1.3%. The trajectory of crack is macroscopically straight and it lies between the contact points of the sample with the compression plates of testing machine. There is extensive cracking prior separation of the sample in its central part. Many satellite cracks are situated ahead the main crack tip. Therefore, fracture behavior of human enamel corresponds to a ductile solid. © 2014 Elsevier B.V.
