Abstract: Taking the effects of geometrical nonlinearity into account,a general theory of composite thin walled bar is established under the combinational deformation of tension,compression and torsion.Focusing on the nonlinear torsion ana1ysis of composite thin walled bar,based on the principle of minimum potential energy,the governing equations of equilibrium as well as all boundary conditions concerned are deduced from the equivalent constitutive equations and general potential energy function.In addition,a solution to the equations of equilibrium is discussed.

Key words: composite, thin walled bar, cylindrical shel theory, geometrical nonlinearity, equivalent constitutive equation, displacement variational principle
