Evaluation of Heterogeneous Densification, Anisotropic Shrinkage and Rheological Behavior of Ceramic Materials during Liquid Phase Sintering by Numerical-Experimental Procedure

The effective shear and bulk viscosity, as well as dynamic viscosity, describe the rheological properties of the ceramic body during the liquid phase sintering process. The rheological parameters depend on the physical and thermo-mechanical characteristics of the material such as relative density, temperature, grain size, diffusion coefficient, and activation energy. Thermal behavior of the cer...

Application of All Ceramic Materials in Dentistry

The daily increase in Patientschr('39') demand for cosmetic treatments has led to dental restorations moving towards the use of all-ceramic materials. The development of all-ceramic restorations over the last decade has revolutionized aesthetic dentistry. Recent advances in ceramic manufacturing and processing methods have led to the evolutionary growth of all-ceramic materials with superior bi...

Modeling of Hygrothermal Damage of Composite Materials

Composite materials have been used extensively in various applications, such as mechanical engineering, aerospace engineering, and aviation thanks to their interesting mechanical properties. However, a substantial drawback in the use of such composite materials is that they absorb a significant amount of moisture when exposed to severe hygrothermal conditions. This factor dramatically affects t...

impact behavior of ceramic-metal armour by al2o3-nano sic nano composite

abstract : alumina (al 2 o 3 ) is one of the most practical ceramics used in making ceramic-metal armours. to improve the properties of alumina, some other materials are added to it. in this paper, sic material as nano powder is added to alumina, and four armour samples of this new ceramic with different volume fractions (v.f. ) including 0%, 5%, 10% and 15% of sic particles are made. then, the...
