Raceway Fatigue Field: Unrolled Subsurface Shear Map

A 2D unrolled-raceway heatmap of Hertzian rolling-contact fatigue: watch the subsurface orthogonal shear stress field accumulate damage cell by cell across the whole raceway circumference as rollers sweep overhead, until a spall opens at the hottest point.

This is a 2D field-native counterpart to the 3D roller-bearing spalling simulator. Rather than orbiting parts around a camera, the entire raceway circumference is unrolled into a flat strip, with true subsurface depth running vertically. Every cell of that strip independently evaluates the real Hertzian orthogonal-shear-stress solution and accumulates its own Lundberg–Palmgren fatigue damage as roller contact patches sweep across it thousands of times, so the whole raceway's fatigue state — not just one tracked point — is visible at once, and a spall opens exactly where and at exactly the subsurface depth the physics says it should.

⚙ Under the hood

A 2D field-native counterpart to the 3D roller-bearing spalling simulator: the raceway circumference is unrolled into a flat strip with true subsurface depth on the vertical axis, and every grid cell independently accumulates real Hertzian-contact fatigue damage as roller contact patches sweep across it, until a spall opens at the exact subsurface depth Lundberg-Palmgren theory predicts.
