Engineering strain Solution

STEP 0: Pre-Calculation Summary

Formula Used

Engineering strain = (Instantaneous length-Initial Length)/Initial Length
𝜀 = (l_i-l₀)/l₀
This formula uses 3 Variables

Variables Used

Engineering strain - Engineering strain is the ratio of change in length to its original length.
Instantaneous length - (Measured in Meter) - The instantaneous length is the length after application of load.
Initial Length - (Measured in Meter) - Initial Length before the application of load.

STEP 1: Convert Input(s) to Base Unit

Instantaneous length: 2 Centimeter --> 0.02 Meter (Check conversion here)
Initial Length: 5000 Millimeter --> 5 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

𝜀 = (l_i-l₀)/l₀ --> (0.02-5)/5

Evaluating ... ...

𝜀 = -0.996

STEP 3: Convert Result to Output's Unit

-0.996 --> No Conversion Required

FINAL ANSWER

-0.996 <-- Engineering strain

Strain hardening exponent

Go Strain hardening exponent = (ln(True stress)-ln(K value))/ln(True strain)

Resolved shear stress

Go Resolved shear stress = Applied stress*cos(Slip plane angle)*cos(Slip direction angle)

Engineering strain

Go Engineering strain = (Instantaneous length-Initial Length)/Initial Length

True strain

Go True strain = ln(Instantaneous length/Initial Length)

Maximum Shear Stress from Tresca Criterion

Go Maximum Shear Stress = (Largest principal stress-Smallest principal stress)/2

True stress

Go True stress = Engineering stress*(1+Engineering strain)

Engineering stress

Go Engineering stress = Load/Cross-sectional Area

Safe stress

Go Safe Stress = Yield Strength/Factor of Safety

True strain from Engineering strain

Go True strain = ln(1+Engineering strain)

Maximum Shear Stress from Von Mises Criterion

Go Maximum Shear Stress = 0.577*Yield Strength

Engineering strain Formula

Engineering strain = (Instantaneous length-Initial Length)/Initial Length
𝜀 = (l_i-l₀)/l₀

Engineering strain

Engineering strain is unitless and is generally expressed as percentage in which the strain value is multiplied by 100. Engineering strain is used practically along with engineering stress.
