True stress Solution

STEP 0: Pre-Calculation Summary

Formula Used

True stress = Engineering stress*(1+Engineering strain)
σ_T = σ*(1+𝜀)
This formula uses 3 Variables

Variables Used

True stress - (Measured in Pascal) - True stress is defined as the load divided by the instantaneous cross-sectional area.
Engineering stress - (Measured in Pascal) - Engineering stress is the ratio of force exerted and the initial area.
Engineering strain - Engineering strain is the ratio of change in length to its original length.

STEP 1: Convert Input(s) to Base Unit

Engineering stress: 10 Megapascal --> 10000000 Pascal (Check conversion here)
Engineering strain: 0.01 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

σ_T = σ*(1+𝜀) --> 10000000*(1+0.01)

Evaluating ... ...

σ_T = 10100000

STEP 3: Convert Result to Output's Unit

10100000 Pascal -->10.1 Megapascal (Check conversion here)

FINAL ANSWER

10.1 Megapascal <-- True stress

(Calculation completed in 00.004 seconds)
