CONVERT A FORCE-DEFLECTION CURVE TO A ENGINEERING STRESS VS STRAIN CURVE BASED

Converts a force-deflection (force-displacement) curve into an engineering stress vs. strain curve by dividing force by the original cross-sectional area and displacement by the original gage length. Use this worker when processing uniaxial coupon test data to produce the standard engineering stress-strain representation needed for material characterization workflows.

When to use

Classification: process.

Tagged: coupon, curve-conversion, engineering-stress-strain, force-deflection, material-testing, uniaxial.

Inputs

Label ID Type Default Required Description
Force Deflection Curve forcedeflectioncurve vector   Input force-displacement curve (X = displacement, Y = force) obtained from a physical coupon test; units must be consistent with the length and area inputs (e.g., mm and N, or in and lbf).
Length length float 1   Original gage length of the specimen used to compute engineering strain (strain = deflection / length); must use the same length unit as the displacement axis of the input curve — defaults to 1 (dimensionless pass-through).
Area area float 1   Original cross-sectional area at the gage section used to compute engineering stress (stress = force / area); must use units consistent with force and desired stress units (e.g., mm² for MPa when force is in N) — defaults to 1 (dimensionless pass-through).

Outputs

Label ID Type Description
curve_forcedeflectiontoengstressstrain_output_1 curve_forcedeflectiontoengstressstrain_output_1 vector Resulting engineering stress vs. strain curve (X = engineering strain [dimensionless], Y = engineering stress [force/area units]), ready for material characterization or calibration workflows.
