The radii of curvature of the contacting bodies are large compared with the radius of the circle of contact.
The dimensions of each body are large compared with the radius of the circle of contact. This allows indentation stresses and strains to be considered independently of those arising from the geometry, method of attachment, and boundaries of each solid.
The contacting bodies are in frictionless contact. That is, only a normal pressure is transmitted between the indenter and the specimen.
