in this paper, the axisymmetric corrugated diaphragm using finite element method will be discussed, so that half of these diaphragms’ cross sections and later the applied pressure will be considered. following this, using the consequent equations and visual basic software, a computer program will be provided which receives the diaphragms’ particulars such as diameter, thickness, pressure and th...

Abstract The aim of the study is to analyse axisymmetric free vibration layered cylindrical shells filled with a quiescent fluid. fluid assumed be incompressible and inviscid. equations vibrations shell fluid, on longitudinal transverse displacement components are obtained using Love’s first approximation theory. solutions functions in separable form obtain system coupled differential terms fun...

A d-dimensional spacetime is “axisymmetric” if it possesses an SO(d−2) isometry group whose orbits are (d−3)-spheres. In this paper, algebraically special, axisymmetric solutions of the higher dimensional vacuum Einstein equation (with cosmological constant) are investigated. Necessary and sufficient conditions for static axisymmetric solutions to belong to different algebraic classes are prese...
