Calculation method

Calculation method

Engineering stress samples (MPa) JSON

Engineering stress=force/original area; engineering strain=extension/original gauge length.

Engineering strain samples (fraction) JSON

Engineering stress=force/original area; engineering strain=extension/original gauge length.

Symbols and units
a
Tensile force samples (N)
b
Extension samples (mm)
c
Original area (mm²)
d
Original gauge length (mm)

Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.

Assumptions & limits

Assumptions & limits

  • User-supplied measurements and assumptions; Engineering stress=force/original area; engineering strain=extension/original gauge length. 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.
Are these inputs private?

These calculations run in your browser. A shared link contains the values you choose to share. Only questions submitted to the separate AI finder are sent to OpenAI.
