Contact Stress Two Rollers Equation and Calculator

Strength / Mechanics of Materials

Contact stresses two rollers in contact.

When a roller is in contact with another roller surface, a line contact is obtained, giving a rectangular contact area of very small width the size of the area depending on the load and materials.

E1, E2, = Young's modulus
F = load
r1, r2 =radii
v1, v2 = Poisson's ratio
