Stress Redistribution Analysis of Piezomagnetic Rotating Thick-Walled Cylinder with Temperature-and Moisture-Dependent Material Properties
In this article, the problem of time-dependent stress redistribution of a piezomagnetic rotating thick-walled cylinder under an axisymmetric hygro-thermo-magneto-electro-mechanical loading is analyzed analytically for the condition of plane strain. Using the constitutive equations, a differential equation is found in which there are creep strains. Primarily, eliminating creep strains, an analyt...
متن کاملelasto-plastic analysis of thick walled tanks subjected to internal pressure
in this article, the elasto-plastic analysis of thick walled fg tanks subjected to internal pressure is elaborated. today, thick walled tanks containing liquids with high pressure are used in the chemical industries. the high internal pressure causes part of the thickness of reservoir to yield; therefore, we need the elasto-plastic analysis. in this study, elasto-plastic behavior of fg cylindri...
متن کاملDesign and analysis of Stress on Thick Walled Cylinder with and with out Holes
The conventional elastic analysis of thick walled cylinders to final radial & hoop stresses is applicable for the internal pressures up to yield strength of material. The stress is directly proportional to strain up to yield point Beyond elastic point, particularly in thick walled cylinders. The operating pressures are reduced or the material properties are strengthened. There is no such existi...
متن کاملElasto-plastic solution for thick-walled spherical vessels with an inner FGM layer
Purely elastic, partially and fully plastic stress states in a thick-walled spherical pressure vessel with an inner functionally graded material (FG) coating subjected to internal and external pressures are developed analytically in this paper. The modulus of elasticity and the uniaxial yield limit of the FG coating layer are considered to vary nonlinearly through the thickness. Using Tresca’s ...
متن کاملCreep Stress Redistribution Analysis of Thick-Walled FGM Spheres
Time-dependent creep stress redistribution analysis of thick-walled FGM spheres subjected to an internal pressure and a uniform temperature field is investigated. The material creep and mechanical properties through the radial graded direction are assumed to obey the simple power-law variation throughout the thickness. Total strains are assumed to be the sum of elastic, thermal and creep strain...
