PR_% = 100*(1-d_s/D_b)
This formula uses 3 Variables

Variables Used

Percent Reduction after Drawing - Percent Reduction after Drawing is a measure used in metalworking processes, particularly in drawing operations, to quantify the amount of deformation.
Outer Diameter of Shell - (Measured in Meter) - Outer Diameter of Shell is the measurement across the widest part of any cylindrical object.
Sheet Diameter - (Measured in Meter) - Sheet Diameter is the diameter of a circular sheet or disc-shaped object. In sheet metalworking, the diameter of a sheet metal blank before any forming or shaping operations are performed on it.

STEP 1: Convert Input(s) to Base Unit

Outer Diameter of Shell: 80 Millimeter --> 0.08 Meter (Check conversion here)
Sheet Diameter: 84.2 Millimeter --> 0.0842 Meter (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

PR_% = 100*(1-d_s/D_b) --> 100*(1-0.08/0.0842)

Evaluating ... ...

PR_% = 4.98812351543942

STEP 3: Convert Result to Output's Unit

4.98812351543942 --> No Conversion Required

FINAL ANSWER

4.98812351543942 ≈ 4.988124 <-- Percent Reduction after Drawing

What is percent reduction in relation to drawing?

The Percent reduction after drawing represent the amount of straining or the
draw-ability of blank material.
The drawing operation relies on the ductility of the blank material. The ductility is affected by the amount of strain a material takes. But there is a limit to which it can be strained. The diameter of the shell to be used is either ID (internal diameter) or OD (outer diameter). But it is convenient to use OD since the cup is normally specified by OD.

How to Calculate Percent Reduction after Drawing?

Percent Reduction after Drawing calculator uses Percent Reduction after Drawing = 100*(1-Outer Diameter of Shell/Sheet Diameter) to calculate the Percent Reduction after Drawing, The Percent Reduction after Drawing represent the amount of straining or the draw-ability of blank material. Percent Reduction after Drawing is denoted by PR_% symbol.

How to calculate Percent Reduction after Drawing using this online calculator? To use this online calculator for Percent Reduction after Drawing, enter Outer Diameter of Shell (d_s) & Sheet Diameter (D_b) and hit the calculate button. Here is how the Percent Reduction after Drawing calculation can be explained with given input values -> 5.04451 = 100*(1-0.08/0.0842).
