This work investigates transient heat conduction in a functionally graded plate (FGM plate) subjected to gradual cooling/heating at its boundaries. The thermal properties of the FGM are assumed to be continuous and piecewise differentiable functions of the coordinate in the plate thickness direction. A linear ramp function describes the cooling/heating rates at the plate boundaries. A multi-lay...

In this work, a 316L stainless steel to Inconel 625 functionally graded material (FGM) was built using different deposition strategies (named as direct and smooth-type interfaces) by Twin-Wire Arc Additive Manufacturing (T-WAAM). This combination of materials is interest in chemical plants, oil & gas, nuclear applications, where high corrosion wear resistance are essential requirements. Althoug...

In this paper a closed form solution for one-dimensional magnetothermoelastic problem in a functionally graded material (FGM) hollow sphere placed in a uniform magnetic field and temperature field subjected to an internal pressure is obtained using the theory of magnetothermoelasticity. Hyper-geometric functions are employed to solve the governing equation. The material properties through the g...

Functionally graded material (FGM) is an advanced class of composite material. In FGM, the volume fraction each constituent can be tailor-made across thickness for desired applications. this paper, analytical solution and numerical simulation free vibration transient heat conduction problem in a functionally pipe are considered. 3D elasticity theory adopted considering effect natural frequency ...

The object of the present paper is to study temperature distribution and thermal stresses of a functionally graded thick hollow cylinder with temperature dependent material properties. All the material properties except Poisson’s ratio are assumed to be dependent on temperature. The nonlinear heat conduction with temperature dependent thermal conductivity and specific heat capacity is reduced t...

Computer simulation and FEM analysis of the stress-strain state thin plates thin-walled cylindrical shells, weakened by a circular hole in presence an annular inclusion functionally graded material (FGM) surrounding it, have been carried out. The influence dimensions FGM-inclusion law change its elastic modulus on concentration parameters shells vicinity is studied. distribution stress strain i...

This article presents the analysis of functionally graded thick hollow cylinders under dynamic load. The functionally graded cylinder is assumed to be made of many subcylinders. Each subcylinder is considered as an isotropic layer. Material’s properties in each layer are constant and functionally graded properties are resulted by suitable arrangement of layers in multilayer cylinder. The proper...

In this article, the axisymmetric mechanical buckling of thin cylindrical shell made of functionally graded material (FGM) is considered. The governing equations for a thin cylinder based on the first-order shell theory and Timoshenko's assumptions are obtained. The equations are derived using the Sanders simplified kinematic relations and the principle of work and energy. The constituent mater...
