The initial researches about variable thickness tube drawing were published by Guillot et. al [1] about experimental studies on the production of variable thickness tubes in the radial and/or axial directions and mechanical properties of tube material after variable thickness drawing.
However, in production of complex geometries, the axial feeding can not have sufficient effect in feeding the material into the zones with more inflation especially if this region is located after the bent region.

In structural dynamics, typical sources of nonlinearities include the geometric nonlinearity results when a structure undergoes large displacements, the inertia nonlinearity derives from nonlinear terms containing velocities and/or accelerations in the equations of motion, the material nonlinearity when the constitutive law relating stresses and strains is nonlinear and the nonlinearity due to damping dissipation, boundary conditions or certain external nonlinear body forces etc.
