Description
Paweł Romanowicz stress-tests a popular fatigue rule for rolling contact, and offers a fix, in a 2026 paper. Wheels, rails, and bearings fail where rolling pressure cycles the metal under the skin. The Dang Van rule is a favorite gauge for such multi-way stress, yet critics say it over-weights squeeze stress and under-reads the true fatigue load. He lines up variants of the rule, all read on the plane where damage should peak.
His own variant counts squeeze stress as harmful as pull, not as a shield. Three checks judge the field: lab data on mixed push and twist, a rival rule famed for rolling accuracy, and a worked roller bearing. The classic rule fails, and dropping squeeze stress alone does not save it. His variant lands closest on all three checks, handing bearing designers a sharper gauge.
