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 paper, first, we intend to determine the relationship between sign of Δc0βy(c0+1), for 1<β<2, and Δy(c0+1)>0, in case assume that Δc0βy(c0+1) is negative. After that, by considering set Dℓ+1,θ⊆Dℓ,θ, which are subsets (1,2), will extend our previous result make Δc0βy(z) Δy(z)>0 (the monotonicity y), where be assumed negative each z∈Nc0T:={c0,c0+1,c0+2,⋯,T} some T∈Nc0:={c0,c0+...

As the statistical power of imaging surveys grows, it is crucial to account for all systematic uncertainties. This normally done by constructing a model these uncertainties and then marginalizing over additional parameters. The resulting high dimensionality total parameter spaces makes inferring cosmological parameters significantly more costly using traditional Monte-Carlo sampling methods. A ...

The development of mathematical models for describing the dynamic behaviours of fluid conveying pipes, micro-pipes and nanotubes under the influence of some thermo-mechanical parameters results into nonlinear equations that are very difficult to solve analytically. In cases where the exact analytical solutions are presented either in implicit or explicit forms, high skills and rigorous mathemat...
