How to Use This Calculator
  1. Enter the Applied Force (N) and Cross-Section Area (mm²) to calculate engineering stress.
  2. Set the Original Gauge Length (mm) and Change in Length ΔL (mm) to calculate engineering strain and Young's Modulus.
  3. Enter the Maximum Force (N) at the highest point on the stress-strain curve for UTS.
  4. Input the Fracture Force (N) — force when the specimen broke — for fracture stress.
  5. Review Engineering Stress (MPa), Young's Modulus (GPa), and Ultimate Tensile Strength to characterize material properties.

How the result changes with Cross-Section Area

What each input means

Applied Force
Force applied to the specimen at the measurement point.
Cross-Section Area
Original cross-sectional area of the test specimen.
Original Gauge Length
Original measured gauge length of the specimen before testing.
Change in Length (ΔL)
Elongation of the gauge length at the current applied force.
Maximum Force
Peak force recorded during the entire tensile test (for UTS calculation).
Fracture Force
Force at the moment of specimen fracture.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Applied Force = 50000, Cross-Section Area = 100, Original Gauge Length = 50, Change in Length (ΔL) = 0.05 = 6 input(s) provided
  2. Calculate Engineering Stress
    Engineering Stress
    500 = 500
  3. Calculate Young's Modulus
    Young's Modulus
    500 = 500
  4. Calculate Engineering Strain
    Engineering Strain
    0.001 = 0.001
  5. Calculate Ultimate Tensile Strength
    Ultimate Tensile Strength
    800 = 800
