Ebene Geometrie, Trigonometrie,inly provided by the helical layer. When the curvature exceeds the critical curvature, the bending moment increases nonlinearly with the curvature, and the bending stiffness is mainly provided by the polymer layer. With the increase of tension and internal pressure, the contact pressure between each
