An algorithmic solution for frictional contact problems subjected to a twisting moment
An efficient numerical procedure is devised and applied for the frictional contact problems subjected to a normal load and a twisting moment. The traction distribution and the region of micro-slip on any shape of contact area can be effectively found by iteratively using a modified linear programming technique. The compliance of the contact system is also evaluated. The numerical solution obtained by the suggested procedure agrees very well with Lubkin’s theory for the circular contact area. The algorithmic solution for disconnected contact areas on semi-infinite bodies is presented to illustrate generality and effectiveness of the proposed numerical procedure.
