It is shown that unlike the zero axial stress in pure material cylinders, it varies along the thickness from minimum to maximum at inner and outer surfaces, respectively.
To achieve this, a constructive method for obtaining closed-form elastic and post-elastic solutions for Functionally Graded Material Cylinders (FGMCs), constituted by an isotropic central core and n arbitrary cylindrically orthotropic hollow phases, is proposed.
The effects of FGM material profile, cylinder thickness, excitation frequency and type on the radiated far-field are examined.
Duralumin alloy (Mass density ρ = 2810 kg/m3, Young modulus E = 7.2×1010 N/m2, Poisson ratio σ = 0.33) is the selected material of cylinder and cantilevers.
The material comprises cylinders of uranium metal, about 150mm long and 35mm in diameter known as "pucks".
§ 173.301 General requirements for shipment of compressed gases and other hazardous materials in cylinders, UN pressure receptacles and spherical pressure vessels.
The effects of locations and materials of cylinders, along with the ground effect, are investigated.
Among the materials are cylinders of propane and pesticides, chlorine being trucked to water purification plants, or gasoline en route to service stations, and rail cars carrying suffocating ammonia to farms for use as fertilizer or to frozen food factories for use as a refrigerant.
This paper investigates the dispersion relations of axisymmetric wave propagation in initially twisted bi-material compound cylinders, within the scope of the piecewise homogeneous body model, utilizing 3D linearized wave propagation theory in an initially stressed body.
The cylinder material consists of metal (Ni) and ceramic (Al2O3), and material properties vary through the thickness direction with a power-law distribution in terms of volume fractions of the constituents.
