Bio-inspired design of dental multilayers: Experiments and model

“…However, their interfaces are sharp, and they typically consist of a top layer of ceramic, a bottom layer of ceramic-filled polymer and an adhesive layer in between ( Fig. 2(a)) (Dabbs et al, 1982;Huang et al, 2005Huang et al, , 2007aLawn et al, 2000;Lee et al, 2002;Niu and Soboyejo, 2006). * Corresponding author at: Department of Mechanical and Aerospace Engineering, Princeton University, Princeton, NJ 08544, United States.…”

Theoretical and experimental analysis of material deformation by microcontact

“…Spherical indentation techniques are used to evaluate the contact damage behavior and damage tolerance properties of materials. [6][7][8][9][10][11][12][13] A constant loading force is applied to the flat surface of the materials using a hard tungsten carbide (WC) ball with a uniform radius. Since cone-shaped fractures are produced during contact between glass lenses, indentation mechanics are extensively used in the analysis and characterization of the mechanical properties of materials.…”

Influences of complex loading and margin geometry: failure of curved brittle layer structures

“…Noteworthy, many studies investigated damage modes in brittle/compliant bi-layers under consideration. These studies virtually concentrated on indentations with hard spheres (Qasim et al 2007a; ( Qasim et al 2004b;Chai et al 1999;Zhao et al 2000;Lawn et al 2002;Rudas et al 2005;Lawn et al 2000a;Jung et al 1999;Lawn et al 2000b;Qasim et al 2004a;Chai and Lawn 2004;Qasim et al 2004c;Zhao et al 2001). They also enabled the identification of various damage modes and the dependencies of critical loads on geometrical variables such as; sample radius (Qasim et al 2004a), coating thickness (Chai and Lawn 2004) and indenter radius (Qasim et al 2004c), as well as a better understanding of the effect of material properties such as interlayer elastic modulus mismatch (Chai et al 1999;Zhao et al 2001).…”

In this series of studies, normal loading configurations have formed the basis for most contact fracture testing, enabled the evaluation of relevant variables with minimum complication (Qasim et al 2007a;Qasim et al 2004b;Chai et al 1999;Zhao et al 2000;Lawn et al 2002;Rudas et al 2005;Lawn et al 2000a;Jung et al 1999;Lawn et al 2000b;Qasim et al 2004a;Chai and Lawn 2004;Qasim et al 2004c;Zhao et al 2001). Most engineering contact problems usually experience a more complex loading, for example, occlusal loading in dental crowns is a special case in point.…”
