A Stress Disturbance Barrier on a Circular Torque Tube blocking the End Effects

Abstract Knowing that the end effects arising from torsional loads will disturb stress distribution in a torque tube, this paper develops means of blocking disturbances where load is applied, such distributions Saint Venant torsion can be maintained. The disturbance barrier (SDB) as an effect shielding considered installed on circular toque tube whose material property with cylindrical orthotropy. In general, SDB comprised two layers: front layer and layer. which optional directly contacted external for enhancing durability, while situated between body mainly disturbances. analysis base state space formalism, uncoupling feature cylindrically orthotropic materials benefit further extension research. It found parameters crucial to determine effective given thickness are orthotropy parameter longitudinal shear modulus. approach how proper constants having clearly provided. As shown by numerical results presented examples, research fully block mathematically expanded power series.
