Calculation method
Calculation method
Offset intersection strain (fraction)
First positive-to-nonpositive intersection of piecewise-linear stress curve with E(strain−offset); reject absent crossing.
Offset yield estimate (MPa)
First positive-to-nonpositive intersection of piecewise-linear stress curve with E(strain−offset); reject absent crossing.

Assumptions & limits
Assumptions & limits
- User-supplied measurements and assumptions; First positive-to-nonpositive intersection of piecewise-linear stress curve with E(strain−offset); reject absent crossing. Supported limits: Finite numeric values bounded to 1e9 magnitude; lists and tables contain 1–100 records unless a stricter bound is stated. Inputs use the units shown. Lists explicitly paired by a method must have matching lengths; independent polynomial coefficient vectors may differ. Respect stated physical, interpolation, policy and computational domain limits.
