Contact Stress Analysis of Multilayered Strands
The calculation method of contact force in contact-zone between adjacent layer wires has been analyzed. The principal radii of curvatures of wires were taken into consideration while obtaining the analytical expressions for contact stesses and sizes of contact surface. Meanwhile, a formular for shear stress of arbitrary point in half-space under contact-zone was derived on basis of the Boussinesq problem and it was simplified by using Gaussian quadrature. According to the results, the stress distribution could be unsderstood more thoroughly and the results is of great importance for studying looseness, fatigue and fretting wear of multilayered strands.
