InputMechanical test data with correctly defined stress and strain.
OutputReviewed mechanical-property calculations and a stress-strain plot.

Workflow

  1. Import the mechanical dataset and map the strain and stress columns.
  2. Confirm units and verify that raw extension or force has already been converted when necessary.
  3. Run mechanical analysis and inspect the automatically selected elastic region and its linear-fit quality.
  4. Review Young’s modulus, the configured offset yield strength, UTS, fracture stress and elongation/fracture strain.
  5. Override the elastic-region endpoint only when the measured curve supports a better defensible interval.
  6. Export the reviewed properties and curve together with specimen geometry, test standard and conditions from the experiment record.

What this workflow helps you do

Calculate common tensile stress–strain properties from data that is already expressed as stress versus strain. NotyPlot normalizes supported stress/strain units and can estimate Young’s modulus, offset yield strength, ultimate tensile strength and fracture/elongation values for review.

Use this workflow when

  • Summarizing engineering stress–strain data from tensile tests.
  • Comparing modulus, yield strength, UTS and elongation across comparable specimens.
  • Checking whether automatic elastic-region selection is appropriate for the measured curve.

What you need before you start

  • A monotonic engineering stress–strain dataset or clearly defined equivalent columns.
  • Known strain units (fraction or percent) and stress units (Pa, kPa, MPa or GPa).
  • Stress rather than raw load, and strain rather than raw extension; geometry is needed upstream if conversion has not already been done.

Step-by-step workflow

  1. Import the mechanical dataset and map the strain and stress columns.
  2. Confirm units and verify that raw extension or force has already been converted when necessary.
  3. Run mechanical analysis and inspect the automatically selected elastic region and its linear-fit quality.
  4. Review Young’s modulus, the configured offset yield strength, UTS, fracture stress and elongation/fracture strain.
  5. Override the elastic-region endpoint only when the measured curve supports a better defensible interval.
  6. Export the reviewed properties and curve together with specimen geometry, test standard and conditions from the experiment record.

What to review in the result

  • The X-axis is strain and the Y-axis is stress, not displacement and load.
  • The elastic-region fit is physically plausible and sufficiently linear.
  • The offset-yield construction intersects the measured curve appropriately.
  • Fracture and UTS values correspond to the intended tensile-test interpretation.

Before you report or export

  • Report engineering versus true stress/strain explicitly.
  • Keep specimen dimensions and test standard outside the plot result when they are needed to reproduce stress or strain conversion.
  • Compare samples only under compatible loading and specimen conditions.

Limitations and interpretation

  • The workflow cannot derive stress from force without specimen cross-sectional area, or strain from extension without gauge length.
  • Automatic elastic-region detection may be unreliable for toe regions, nonlinear materials or noisy data.
  • Mechanical properties depend on specimen geometry, test method, strain rate and data processing, not only the plotted curve.
