in this article, thermal stability of beams made of functionally graded material (fgm) is considered. the derivations of equations are based on the one-dimensional theory of elasticity. the material properties vary continuously through the thickness direction. tanigawa's model for the variation of poisson's ratio, the modulus of shear stress, and the coefcient of thermal expansion is...
Co-extrasion involves extrasion of multiple layers at the same time. Functionally graded materials comprising various layers with different properties can be produced through co-extrusion. Rheological control is vital for successful co-extrusion of layered cement-based materials. The paste flow in the barrel and the die land in a ram extruder should be plug-like, while the paste should be shear...
Quasicrystal materials have aroused extensive attentions of researchers due to their excellent properties. In this paper, for the first time, functionally graded two-dimensional piezoelectric QC wedges and spaces which subjected line force, charge or dislocation are investigated. By virtue equilibrium constitutive equations, real form expressions stresses displacements directly derived without ...
