In elastic stage, these two stresses must satisfy following equations α ττ G yx xz yz 2= ∂ ∂ − ∂ ∂ , 0= ∂ ∂ + ∂ ∂ yx yz xz ττ (1) where G is the shear module of the isotropic material; α is the torsion angle along the unit length of the bar. τxz and τyz can be expressed in terms of stress function Φe as ye xz ∂ Φ∂ =τ , xe yz ∂ Φ∂ −=τ (2) Substitution equation (2) into the first expression of equation (1) yields αG yx e e e 22 2 2 2 2 −=      ∂Φ∂ + ∂Φ∂ =Φ∇ (3) And the elastic torque Te can be evaluated by ∫∫ Φ= A e e dxdy T 2 (4) So, at this stage, once the stress function is obtained, the stresses and the torque can be determined.
