【Abstract】 In this paper, accurate incremental formulation of member element increments is derived with definition of kirchoff’s stress tension and Green’s strain tension based on total Lagrangian coordinates. The numerical examples in this paper show that the method can be used to analysis large deflection of space trusses.更多还原
