【 摘 要 】

The torsion problems for aluminum alloy rods with circular cross section are solved. The rods are cut out from a transversely-isotropic plate with reduced resistance to creep strain in the direction of 45° to the normal direction of plate. Approximate estimates and finite element analysis show that the warping of the cross-section occurs when the rods are cut out in the longitudinal direction. In this case the value of torsion angle exceeds more than three times the value of torsion angle calculated in solving the isotropic problem. The analytical solution and finite element analysis for the rods cut out in the normal direction of plate show that the warping of the cross-section is missing, but the value of torsion angle s greater by an order of the value of torsion angle calculated in solving of the isotropic problem.
