000015094 520__ $$2eng$$aTooth enamel, although having nominal material properties similar to glass, is able to sustain repeat contact loading under harsh conditions from food processing, a critical function for survival. To understand how individual material phases of enamel are combined to impart tooth resilience, a robust characterization of material properties under actual loading conditions and valid failure and fracture analyses need be conducted. In this work, some basic macro scale deformation and fracture characteristics of tooth enamel under occlusal loading are established. This information is then used in a fracture mechanics analysis to produce critical loads for tooth failure. The results show that the most critical strength factors are enamel thickness and enamel material nonlinearity.
