1 CONTACT DAMAGE IN DENTAL MULTILAYERS: FROM EXPERIMENTS TO MECHANISM-BASED MODELS AND BIOINSPIRED DESIGN

Abstract

This paper presents the results of a combined experimental and computational study of contact damage in dental multilayers. Hertzian indentation experiments are used to explore the basic mechanisms of contact-induced deformation and pop-in. The insights developed in the experiments are then used to guide the development of mechanism-based mechanics models for the prediction of deformation and cracking in dental multilayers. Finally, bioinspired and mechanism-based models are proposed for the design of functionally graded multilayers that are more resistant to deformation and cracking.
