Contact Stress Two Rollers Same Material

Strength / Mechanics of Materials

Contact stresses two rollers in contact.

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

Where:
E_{1, 2} = Young's modulus
F = load
r₁, r₂ =radii
v = Poisson's ratio
