«Measurement of the Fracture Toughness and Mechanical Properties of Hydroxyapatite Using Vickers Indentation Technique »
0571–0584 (2021)

PACS numbers: 62.20.D-, 62.20.mm, 62.20.Qp, 62.25.Mn, 68.37.Hk, 81.40.Np, 83.60.Uv

The fracture toughness is a good asset that identifies a one of the important properties, namely, a brittleness of the hydroxyapatite material and the fracture strength. The applied load and the crack geometry are independent values for measuring the fracture toughness by using Vickers indentation technique. The kind of cracks observed in the hydroxyapatite sample is median–radial cracks at different ranges of applied loads using Vickers indentation method. The scanning electron microscope is used to observe and measure the crack length and visualize the crack tip and its development. The residual stress on the hydroxyapatite sample surface is identified from measuring fracture toughness, which is affected by small subcritical cracks, which are created under loading. The scanning electron microscope is used in this technique for showing the crack tip with high quality as well as crack profile and this process, which give a high accurate for calculating the fracture toughness. The mechanical properties of the hydroxyapatite samples are measured. Young’s modulus and Poisson’s ratio are measured using ultrasonic method and are used for calculation of the accuracy fracture-toughness values, and hardness is measured using Vickers indentation. Vickers crack opening displacement is measured from the mechanical properties (fracture toughness and Young’s modulus) and the crack length, which give a good predication for measuring fracture toughness of the hydroxyapatite sample.
