Derivation of Geometrieal Nonlinear Stiffness Matrix for Space Beam Element

Abstract:

A space beam element is derived for geometrically nonlinear analysis based on the principle of minimum potential energy principle. The impact of high-order nonlinear is considered by introducing the axial deformation into the stiffness matrix. The large displacement matrix is divided into four and the initial stress matrix into three submatrix
