Structural integrity of engineering components made of functionally graded materials [PDF]

, 2008
Functionally graded materials (FGM) are composite materials with microstructure gradation optimized for the functioning of engineering components. For the case of fibrous composites, the fibre density is varied spatially, leading to variable material ...

Statistical Analysis of Multiscale Boundary Element on Heat Transfer of Functionally Graded Materials

Hangkong gongcheng jinzhan, 2018
Functionally graded materials have continuous distributions of physical properties over the entire structure. The graded layers with continuous material characteristics also greatly reduce the stress concentration at interfaces between distinct material ...

Bending and free vibration of functionally graded beams using various higher-order shear deformation beam theories [PDF]

, 2012
In this paper, various higher-order shear deformation beam theories for bending and free vibration of functionally graded beams are developed. The developed theories account for higher-order variation of transverse shear strain through the depth of the ...
