Stress-strain relationship plots applied stress vs. resulting strain; reveals elastic, yield, and ultimate strength regions.

Stapsgewijze handleiding

  1. 1Input stress-strain data points
  2. 2Calculate properties: elastic limit, yield stress, ultimate stress, fracture stress
  3. 3Plot diagram showing material behavior

Uitgewerkte voorbeelden

Invoer
Mild steel: linear elastic region until ~250 MPa, plastic region, ultimate ~450 MPa
Resultaat
Ductile material with clear yield point

Veelgemaakte fouten om te vermijden

  • Confusing engineering vs. true stress/strain
  • Not accounting for strain rate effects

Veelgestelde vragen

What's difference between yield and ultimate strength?

Yield: permanent deformation begins, Ultimate: maximum stress before necking.
