Calculation of Sealant Shear Stress and Rotation Caused by Torsion Momentum M
Assuming a torsion momentum M acting around the center axis, this causes a shear stress in the sealant and a rotation of the structural point, as shown in Fig. 27.
The nature of the circular geometry and the momentum balance around the center results in the following relationships.
Shear stress as a function of the radius
s (r) = Г ‘ a ‘ G (A17)
Maximum displacement at the edge
32 ■ e ■ M n ■ G ■ D4
Solving the above equations (Eqs A17-A19) results in Angle of rotation
