Fabrication of strong and tough alumina ceramic with isotropic textured microstructure at low temperature

Journal of Materials Research and Technology, 2023
High strength and toughness are contradictory in ceramic materials. Improving the toughness of ceramics through the introduction of a ductile phase to dissipate energy is usually at the sacrifice of strength, stiffness, and the ability to operate at high

An elastoplastic framework for granular materials becoming cohesive through mechanical densification. Part I - small strain formulation

, 2010
Mechanical densification of granular bodies is a process in which a loose material becomes increasingly cohesive as the applied pressure increases. A constitutive description of this process faces the formidable problem that granular and dense materials ...
