Pressure Between Two Bodies in Contact
In this chapter we discuss a special problem of elasticity theory, the so called contact problem. Suppose that two elastic bodies are in contact at a single point. If the bodies are pressed with a force, say F, the contact, because of deformation, will not be in a single point but will be over a small area of the surface of each body. This surface is called the pressure surface. The curve that bounds the pressure surface is called the pressure contour. The basic problem of contact mechanics is to determine the pressure surface for a given force F and the distribution of stresses within the pressure surface.
