Total Elongation of Stock Solution

STEP 0: Pre-Calculation Summary

Formula Used

Total Stock or Workpiece Elongation = Initial Cross Sectional Area/Final Cross Sectional Area
E = A_i/A_f
This formula uses 3 Variables

Variables Used

Total Stock or Workpiece Elongation - Total Stock or Workpiece Elongation is the change in the length of the stock after the rolling process.
Initial Cross Sectional Area - (Measured in Square Meter) - The Initial Cross Sectional Area is the area at the start of operation of a portion of material exposed after cutting it transversely.
Final Cross Sectional Area - (Measured in Square Meter) - The Final Cross Sectional Area is the area at the end of operation of a portion of material exposed after cutting it transversely.

STEP 1: Convert Input(s) to Base Unit

Initial Cross Sectional Area: 60 Square Centimeter --> 0.006 Square Meter (Check conversion here)
Final Cross Sectional Area: 9 Square Centimeter --> 0.0009 Square Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

E = A_i/A_f --> 0.006/0.0009

Evaluating ... ...

E = 6.66666666666667

STEP 3: Convert Result to Output's Unit

6.66666666666667 --> No Conversion Required

FINAL ANSWER

6.66666666666667 ≈ 6.666667 <-- Total Stock or Workpiece Elongation

Pressure Considering Rolling Similar to Plane-Strain-Upsetting Process

Go Pressure Acting while Rolling = Strip Width of Spiral Spring*(2*Flow Stress of Work Material)/sqrt(3)*(1+(Frictional Shear Factor*Roller Radius*pi/180*Bite Angle)/(2*(Thickness before Rolling+Thickness after Rolling)))*Roller Radius*pi/180*Bite Angle

Initial Stock Thickness given Pressure on Rolls

Go Initial Stock Thickness = (Mean Yield Shear Stress of Work Material*Thickness at given Point*exp(Friction Coefficient in Rolling Analysis*(Factor H at Entry Point on Workpiece-Factor H in Rolling Calculation)))/Pressure Acting on Rolls

Factor H used in Rolling Calculations

Go Factor H in Rolling Calculation = 2*sqrt(Roller Radius/Thickness after Rolling)*atan(sqrt(Roller Radius/Thickness after Rolling))*Angle made by Point Roll Center and Normal

Angle Subtended by Neutral Point

Go Angle subtended at Neutral Point = sqrt(Thickness after Rolling/Roller Radius)*tan(Factor H at Neutral Point/2*sqrt(Thickness after Rolling/Roller Radius))

Factor H at Neutral Point

Go Factor H at Neutral Point = (Factor H at Entry Point on Workpiece-ln(Thickness before Rolling/Thickness after Rolling)/Friction Coefficient in Rolling Analysis)/2

Total Elongation of Stock

Go Total Stock or Workpiece Elongation = Initial Cross Sectional Area/Final Cross Sectional Area

Projected Area

Go Projected Area = Width*(Roller Radius*Change in Thickness)^0.5

Maximum Reduction in Thickness Possible

Go Change in Thickness = Friction Coefficient in Rolling Analysis^2*Roller Radius

Bite Angle

Go Bite Angle = acos(1-Height/(2*Roller Radius))

Projected Length

Go Projected Length = (Roller Radius*Change in Thickness)^0.5

Total Elongation of Stock Formula

Total Stock or Workpiece Elongation = Initial Cross Sectional Area/Final Cross Sectional Area
E = A_i/A_f

How to find Total Elongation after Rolling Process?

Total elongation means the increase in dimensions of the stock after the Rolling process. It can be found by dividing the initial area of the cross section by the final area of cross section of the rolled product. The elongation can be defined as total for all the passes or that for each pass separately.

How to Calculate Total Elongation of Stock?

Total Elongation of Stock calculator uses Total Stock or Workpiece Elongation = Initial Cross Sectional Area/Final Cross Sectional Area to calculate the Total Stock or Workpiece Elongation, The Total Elongation of Stock can be calculated by dividing the initial area of the cross-section by the final area of the cross-section of the rolled product, it represents the change in the length of the stock after the rolling operation. Total Stock or Workpiece Elongation is denoted by E symbol.

How to calculate Total Elongation of Stock using this online calculator? To use this online calculator for Total Elongation of Stock, enter Initial Cross Sectional Area (A_i) & Final Cross Sectional Area (A_f) and hit the calculate button.
