Bending Force Solution

Follow our step by step solution on how to calculate Bending Force?

FIRST Step Consider the formula

F B = \frac{K bd \cdot L b \cdot σ ut \cdot {t blank}^{2}}{w}

Next Step Substitute values of Variables

∴

F B = \frac{0.031 \cdot 1.01mm \cdot 450N/mm² \cdot {8.99mm}^{2}}{34.9916mm}

Next Step Convert Units

∴

F B = \frac{0.031 \cdot 0.001m \cdot 4.5E+8Pa \cdot {0.009m}^{2}}{0.035m}

Next Step Prepare to Evaluate

∴

F B = \frac{0.031 \cdot 0.001 \cdot 4.5E+8 \cdot {0.009}^{2}}{0.035}

Next Step Evaluate

∴

F B = 32.5425001457492N

LAST Step Rounding Answer

∴

F B = 32.5425N

How to Evaluate Bending Force?

Bending Force evaluator uses Bending Force = (Bending Die Constant*Bent Part Length*Ultimate Tensile Strength*Blank Thickness^2)/Width between Contact Points to evaluate the Bending Force, Bending Force is required to deform and bend the component in the desired shape during a bending operation. Bending Force is denoted by F_B symbol.

How to evaluate Bending Force using this online evaluator? To use this online evaluator for Bending Force, enter Bending Die Constant (K_bd), Bent Part Length (L_b), Ultimate Tensile Strength (σ_ut), Blank Thickness (t_blank) & Width between Contact Points (w) and hit the calculate button.

FAQs on Bending Force

What is the formula to find Bending Force?

The formula of Bending Force is expressed as Bending Force = (Bending Die Constant*Bent Part Length*Ultimate Tensile Strength*Blank Thickness^2)/Width between Contact Points. Here is an example- 32.5425 = (0.031*0.00101*450000000*0.00899^2)/0.03499162.

How to calculate Bending Force?

With Bending Die Constant (K_bd), Bent Part Length (L_b), Ultimate Tensile Strength (σ_ut), Blank Thickness (t_blank) & Width between Contact Points (w) we can find Bending Force using the formula - Bending Force = (Bending Die Constant*Bent Part Length*Ultimate Tensile Strength*Blank Thickness^2)/Width between Contact Points.
