Assumptions & limits
Assumptions & limits
- Circular stone only; neutral line assumed at strip mid-thickness. Strip height and forming/bending allowance remain supplied; no oval/polygon or fit guarantee. Supported limits: All numeric inputs must be finite. Only the explicitly described mathematical scenario is supported.
