Vibration analysis of functionally graded material (FGM) grid systems

open access: bronzeSteel and Composite Structures, 2015
The paper considers the free vibration analysis of FGM grid systems. Up to now, very little work has been done on this type of system and the paper aspires to fill this gap. Based on the hybrid-stress finite element formulation free vibration solutions for FGM grid systems of various aspect ratios, different types of gradations functions, and support ...

Densification of Ti/HA Functionally Graded Material (FGM) by SPS.

open access: diamondJournal of the Japan Society of Powder and Powder Metallurgy, 2000
Composites of hydroxyaptite (HA) and titanium (Ti) decompose for few days. The composite prepared from titanium hydride (TiH) and HA is stable for more than a year, but its toughness is very low. Functionally graded materials (FGMs) fabricated from TiH and HA by SPS cracked in the HA layer by the residual stress due to thermal expansion mismatch ...

Additive Manufacturing of Functionally Graded Materials (FGM) parts

open access: gold, 2013
Les pièces multimatériaux à gradient fonctionnel (Functionally Graded Materials - FGM) sont des structures dont la composition et la microstructure du matériau changent graduellement à l'intérieur de la pièce. Cette distribution des matériaux permet de réaliser des gradients de propriétés au niveau mécanique, physique, chimique, etc.

Multi-scale modeling of functionally graded materials (FGMs) using finite element methods

open access: green, 2015
Functionally Graded Materials (FGMs) have a gradual material variation from one material character to another throughout the structure. Applications of these types of materials have significant advantages in civil and mechanical systems including thermal systems.

Potential functions of thermoelastodynamic problems for transversely isotropic functional graded materials [PDF]

open access: yesمهندسی عمران شریف, 2023
Functionally graded materials are the novel class of advanced composite structures with variable properties in one or more directions. The mechanical properties of Functionally Graded Materials (FGM) such as Poisson’s ratio, Young’s modulus of elasticity,

Clinical periodontal diagnosis

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases include pathological conditions elicited by the presence of bacterial biofilms leading to a host response. In the diagnostic process, clinical signs such as bleeding on probing, development of periodontal pockets and gingival recessions, furcation involvement and presence of radiographic bone loss should be assessed prior ...
