"When two non-conforming solids are brought into contact they touch initially at a single point or along a line. Under the action of the slightest load they deform in the vicinity of their point of first contact so that they touch over an area which is finite though small compared with the dimensions of the two bodies." (Johnson, 1987)
Results
The contact traction contour on the rail shown in Figure 5. The quality of the results is maintained well with FASTCONT.
