🛡️ Contact Stresses (Hertzian Sub-Surface Shear Stress <180 MPa, Preventing Spalling)

Rotary Drum Tire Contact Stress & Machining Calculator

Calculate Hertzian sub-surface peak shear stresses ($ au_{max} < 180 ext{ MPa}$) across cylindrical contact patches between riding rings and trunnion rollers: plan on-site in-situ rotary grinding and re-machining of work-hardened spalled outer tire surfaces, and heavy equipment refurbishment profits.
