the major reason for the prediction of thermodynamic properties of mercury lies in the fact that itsintermolecular interactions highly depend on temperature and density. internal pressure is a good criterion toinvestigate the density dependence of the interatomic interactions. because its physical base is a forcetending to close together the molecules that is intermolecular interactions, and as...

free vibration of simply supported circular cylindrical shell made of functionally graded material (fgm) under internal pressure was investigated. the effective material properties are assumed to vary continuously along the thickness direction according to a volume fraction power law distribution. first order shear deformation theory based on love's first approximation theory was utilized in th...

thermo-elasto-plastic analyses of thick-walled spherical tanks made of functionally graded materials are investigated analytically. these tanks are subjected to positive or negative temperature gradient and internal pressure loadings separately or simultaneously. the power law modeling has been used for through-the-thickness variation of mechanical properties. von mises yield criterion and elas...

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...
