based on three-dimensional theory of elasticity, static analysis of functionally graded carbon nanotube reinforced composite (fg-cntrc) cylindrical panel subjected to mechanical uniformed load with simply supported boundary conditions is carried out. in the process, stress and displacement fields are expanded according to the fourier series along the axial and circumferential coordinates. from ...

in this article, thermo-elastic-behavior of a thick-walled cylinder made from a polystyrene nanocomposite reinforced with functionally graded (fg) single-walled carbon nanotubes (swcnts) was carried out in radial direction while subjected to a steady state thermal field. the swcnts were assumed aligned, straight with infinite length and a uniform layout. two types of variations in the volume fr...

Abstract This research work presents an innovative utility of Functionally Graded Aluminum Matrix Composite with Silicon Carbide as a friction material in clutches’ plate since it has acceptable coefficient and high wear resistance which may lead to longer working life. Composite’s properties are calculated using rule-of-mixture power law, simulated layered geometry. Clutches designed based on ...

A new mathematical model of a porous functionally graded micro/nano-beam under the action Casimir force and Coulomb is constructed in this paper. The construction takes into account Euler-Bernoulli kinematic model. dimensional-dependent parameter taken by modified moment theory elasticity. variational, differential equations, boundary initial conditions are derived from Ostrogradsky-Hamiltonian...

In this study, the manufacturability of new types steel-steel composites on an open-architecture laser powder bed fusion (LPBF) system is demonstrated. A hard martensitic stainless tool steel 440C and a soft austenitic 316L are combined in “multi-material” component with discrete continuous material gradients. Interface engineering accomplished through heat treatment to induce phase transformat...

Delamination fracture of a two-dimensional functionally graded multilayered four-point bending beam that exhibits non-linear behaviour of the material is analyzed. The fracture is studied analytically in terms of the strain energy release rate. The beam under consideration has an arbitrary number of layers. Each layer has individual thickness and material properties. A delamination crack is loc...
