Contact Stress Sphere on Concave Surface

Contact stresses sphere in contact conical surface.

When a ball is in contact with a concave or convex surface, a small contact area is formed, the size of the area depending on the load and materials.

E = Young’s modulus
F = load
r1, r2 =radii
v = Poisson’s ratio
