AI Thread Summary
To calculate the instantaneous impact force in a pendulum impact tester, one needs to know the nominal potential energy, drop height, and impact velocity. The weight of the hammer and the material being tested can also provide useful information. However, determining the impact force without knowing the impact time or acceleration is problematic. Some participants in the discussion suggest that calculating the instantaneous impact force may not be feasible. Overall, the consensus indicates that additional information or methods may be necessary for an accurate calculation.

TL;DR Summary
I need to calculate instantaneous impact force in the lower dead center of Charpy hammer.
Hi there,
First of all i want to apologize for my english, but i am not from english speaking country, so i am not perfect in it.
Now for the question. I need to calculate instantaneous impact force in the lower dead center of Charpy hammer knowing nominal potential energy in lower dead center, drop heigh and impact velocity. I can also get informations like weight or which material i am going to break (if that helps). I am not saying that i can't get another informations, but i just can't figure out how to calculate this without knowing the impact time from release or acceleration. So how can i calculate this or eventually what another informations do i need?

Thank you for all the answers.

edit: i have searched some posts here, but i have never found any answers

What you are asking is impossible. There is no way to calculate this.
 

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly

Thread 'What's the most likely cause for this carbon seal crack?'

We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
