Finite Element Analysis of Static Geometry Nonlinear about Cantilever Beam
Abstract: The finite element model of geometry nonlinearity about cantilever has been introduced in this paper. The relation of strain-stress about cantilever has been deduced (in range of linearity). Based on this, using finite element analysis soft, the static geometry nonlinearity of cantilever beam structure has been finitely analyzed. The study finds that the existing strain-stress relation is not linear relation when the cantilever beam structure shows the geometry nonlinearity after receiving large deformation, but is nonlinearity, and that the theoretical derivation must be computed by using nonlinear system of equations. But the solution of nonlinear equations can use increment means of large distortion question, which is T.L means (Lagrange means).
