چکیده مقاله

Nanoindentation has recently appeared as a powerful tool for measuring of the nano and micro-scale mechanical properties of bio-tissues and other biomaterials. By continuing of advancements in indentation data analysis, will increase the method’s utility in the characterization of biomaterials. However, the viscoelastic constitutive effects of bio-tissues during the nanoindentation are seldom considered rigorously, which they are very significant in viscoelastic contact mechanics. In this paper, we review the current state of nanoindentation, where information on material behaviour and properties in micro-structural features is obtained from the indenter load and depth measuring continuously during the loading and unloading procedure. In the following, we present adaptations for indentation of especially bone and teeth, and state a lately developed method for improving the viscoelastic constitutive effects during the nanoindentation.
