The purpose of the study was to verify the effects of a number of materials' parameters (crystalline content; Young's modulus, E; biaxial flexure strength, sigma(i); Vickers hardness, VH; fracture toughness, K-Ic; fracture ...

Computer-aided design/computer-aided manufacturing (CAD/CAM) materials were submitted to thermocycling, to identify changes in mechanical behavior. Four CAD/CAM materials were divided in four subordinate groups (n=9): (1) ...

The self-affine behavior of Brazilian disk test titanium oxide specimens for K(Ic) measurement was investigated from 3D elevation maps obtained at regular intervals following crack extension. The bifractal approach could ...

The aim of this study is to evaluate the machinability of four CAD/CAM materials (n = 13) assessed by brittleness index, Vickers hardness, and fracture toughness and interaction among such mechanical properties. The materials ...

O presente trabalho apresenta uma metodologia confiável e de execução rápida para a avaliação do desgaste abrasivo entre as cerâmicas Duceram e Vita nas resinas compostas Z-100 e Charisma. Estes materiais são amplamente ...
