    Force
In summary, the conversation is about determining the amount of force needed to punch a circular disc through Aluminum 7075. The formula proposed is P=(LTS)/2000, where P represents press tonnage, L is the circumference of the circle, T is the thickness, and S is the ultimate tensile strength of the material. The speaker also suggests considering the failure mode of the material and choosing a suitable modulus.

I am trying to figure out how to get the punch through force of an object. However, the data that I have pulled up have all contradicted each other.

Basically, How much force (in tons) is needed for an circular disc to be punched through Aluminum 7075.

What I have already came up with is:

P= (LTS)/2000

P=Press tonnage
L=circumference of circle
T=thickness
S=material strength in (ultimate tensile strength)


If anyone has any thoughts about this, could you please get back to me on this!

Thank you!

Think about the "failure" mode of the material you're punching; is it tensile, compressive, torsional, shear, or what, and then pick a modulus.

Thanks!

Thank you Bystander,

It was ultimate tensile strength, for a certain aluminum.

Strength (psi) x Area = pressure(pounds)
 

FAQ: Calculating Punch Through Force for Aluminum 7075

1. What is punch through force and why is it important in aluminum 7075?

Punch through force refers to the amount of force required to penetrate or punch through a material. In the case of aluminum 7075, it is important because it is a commonly used high strength alloy and understanding its punch through force can help determine its suitability for various applications.

2. How is punch through force calculated for aluminum 7075?

Punch through force can be calculated using the formula F = A * σ, where F is the punch through force, A is the area of the punch, and σ is the ultimate tensile strength of aluminum 7075. This formula assumes a simplistic, ideal scenario and may need to be adjusted for real-world applications.

3. What factors can affect the punch through force of aluminum 7075?

There are several factors that can affect the punch through force of aluminum 7075, including the thickness and shape of the material, the speed and angle of the punch, and the presence of any pre-existing defects or imperfections in the material.

4. How does the punch through force of aluminum 7075 compare to other materials?

The punch through force of aluminum 7075 is relatively high compared to other materials, especially when considering its low density. It is commonly used in aerospace, automotive, and military applications due to its high strength-to-weight ratio.

5. Can punch through force be used to predict the failure of aluminum 7075?

While punch through force can provide valuable information about the strength and suitability of aluminum 7075, it should not be solely relied upon to predict failure. Other factors such as fatigue, corrosion, and environmental conditions should also be taken into consideration.
