ADHESION AND CREEP ZONE INVESTIGATION OF PLANAR ELASTIC STEEL ON STEEL CONTACTS WITH FRICTION--A FINITE ELEMENT ANALYSIS

To further understand the problems of tractive contact with friction, and the behavior of adhesion and creep (or slip) zones in such contacts, the relative movement and stresses between the contact surfaces of rectangular block and plate of steel under vertical and horizontal line loads is analyzed using a modification of Wilson's plane stress finite element program. Slipping of one body with respect to another is accomplished by an iterative nodal splitting technique. Solutions are obtained separately for normal and inclined loads for various coefficients of friction. It is shown that when only a normal load is acting, the adhesion zone is centrally located with the creep zone symmetrically placed on both sides. The larger the friction coefficient, the larger is the size of the adhesion zone until for a high enough coefficient, the entire contact area becomes the adhesion zone. When both normal and lateral loads are acting, the adhesion zone moves away from the center in a sense opposite to the direction of the external lateral load to an extent depending on the ratio of the vertical to lateral loads. For values above a certain ratio, the adhesion zone remains at the edge of the contact area. Relative size and movement of the adhesion and creep zones for different friction coefficients and horizontal to vertical load ratios are calculated and plotted.
