Statement or the problem of geometrically non-linear deformation of space trusses on the basis of Finite Element Method
A unified and general concept for the geometrically nonlinear analysis of structures with large displacements and rotations is further developed in this article. The governing equations for the determination of the displacements and the reactions at the nodes of the truss as well as the load factor for the load pattern are derived. Truss hypotheses and semi-analytical integration are used to reduce the three-dimensional nonlinear theory of elasticity to a space truss theory.
