Radial strain for rotating thin disc Solution

STEP 0: Pre-Calculation Summary

Formula Used

Radial strain = (Final Radial Width-Initial Radial Width)/Initial Radial Width
e_r = (dr_f-dr)/dr
This formula uses 3 Variables

Variables Used

Radial strain - Radial strain is the change in length per unit length in a direction radially outward from the charge.
Final Radial Width - (Measured in Meter) - Final Radial Width is the radial width under radial strain.
Initial Radial Width - (Measured in Meter) - Initial Radial Width is the radial width without any strain.

STEP 1: Convert Input(s) to Base Unit

Final Radial Width: 9 Millimeter --> 0.009 Meter (Check conversion here)

Radial stress given initial radial width of disc

Go Radial Stress = ((Increase in Radial Width/Initial Radial Width)*Modulus Of Elasticity Of Disc)+(Poisson's Ratio*Circumferential Stress)

Radial stress given radius of disc

Go Radial Stress = (Circumferential Stress-((Increase in radius/Disc Radius)*Modulus Of Elasticity Of Disc))/(Poisson's Ratio)

Radial stress for disc given circumferential strain on disc

Go Radial Stress = (Circumferential Stress-(Circumferential strain*Modulus Of Elasticity Of Disc))/(Poisson's Ratio)

Radial stress given radial strain on disc

Go Radial Stress = (Radial strain*Modulus Of Elasticity Of Disc)+(Poisson's Ratio*Circumferential Stress)

Radial strain on disc given stresses

Go Radial strain = (Radial Stress-(Poisson's Ratio*Circumferential Stress))/Modulus Of Elasticity Of Disc

Radial strain for rotating thin disc
