Variables Used

Drawing Force - (Measured in Pascal) - Drawing force is the force required to be exerted by the punch or ram on the blank to form shells of desired shape.
Outer Diameter of Shell - (Measured in Meter) - Outer Diameter of Shell refer to the measurement across the widest part of any cylindrical object.
Blank Thickness of sheet - (Measured in Meter) - Blank Thickness of Sheet is the given thickness of the stock material or blanks.
Yield Strength - (Measured in Pascal) - Yield strength can be defined as follows, a straight line is constructed parallel to elastic portion of stress–strain curve at strain offset of 0.002.
Blank or sheet Diameter - (Measured in Meter) - Blank or Sheet Diameter is the diameter of the blank used.
Cover Friction Constant - Cover Friction Constant takes into account the losses and deviation from calculated value due to friction.

STEP 1: Convert Input(s) to Base Unit

Outer Diameter of Shell: 79.9913 Millimeter --> 0.0799913 Meter (Check conversion here)
Blank Thickness of sheet: 1.13 Millimeter --> 0.00113 Meter (Check conversion here)
Yield Strength: 35 Newton per Square Millimeter --> 35000000 Pascal (Check conversion here)
Blank or sheet Diameter: 84.25 Millimeter --> 0.08425 Meter (Check conversion here)
Cover Friction Constant: 0.6 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_d = pi*d_O*t_bl*σ_y*(d_bk/d_O-C_f) --> pi*0.0799913*0.00113*35000000*(0.08425/0.0799913-0.6)

Evaluating ... ...

P_d = 4504.71070248844

STEP 3: Convert Result to Output's Unit

4504.71070248844 Pascal -->0.00450471070248844 Newton per Square Millimeter (Check conversion here)

FINAL ANSWER

0.00450471070248844 ≈ 0.004505 Newton per Square Millimeter <-- Drawing Force

Drawing Force for Cylindrical Shells

Go Drawing Force = pi*Outer Diameter of Shell*Blank Thickness of sheet*Yield Strength*(Blank or sheet Diameter/Outer Diameter of Shell-Cover Friction Constant)

Blank Size for Drawing Operation

Go Blank or sheet Diameter = sqrt(Outer Diameter of Shell^2+4*Outer Diameter of Shell*Height of Shell)

Blank Diameter from Percent Reduction

Go Blank or sheet Diameter = Outer Diameter of Shell*(1-Percent Reduction after Drawing/100)^(-1)

Shell Diameter from Percent Reduction

Go Outer Diameter of Shell = Blank or sheet Diameter*(1-Percent Reduction after Drawing/100)

Percent Reduction after Drawing

Go Percent Reduction after Drawing = 100*(1-Outer Diameter of Shell/Blank or sheet Diameter)

Drawing Force for Cylindrical Shells Formula

Drawing Force = pi*Outer Diameter of Shell*Blank Thickness of sheet*Yield Strength*(Blank or sheet Diameter/Outer Diameter of Shell-Cover Friction Constant)
P_d = pi*d_O*t_bl*σ_y*(d_bk/d_O-C_f)
