Static, vibration and buckling analysis of axisymmetric circular plates using finite elements

摘要: Abstract The static, vibration, and buckling analysis of axisymmetric circular plates using the finite element method is discussed. For static analysis, stiffness matrix a typical annular plate derived from given displacement function appropriate constitutive relations. By assuming that function, which an exact solution equation ▿ 2 W = 0, closely represents vibration modes, mass stability coefficient matrices for are also constructed. In addition to element, stiffness, mass, closure included complete (no center hole). As extension symmetrical bending having polar orthotropy given.
