SUMMARY

The discussion focuses on calculating the instantaneous impact force in a Charpy hammer at the lower dead center using known variables such as nominal potential energy, drop height, and impact velocity. Participants highlight the challenge of determining this force without knowledge of impact time or acceleration. The consensus is that calculating instantaneous impact force is not feasible with the provided information, as essential data is missing.

PREREQUISITES
  • Understanding of Charpy impact testing and its applications
  • Familiarity with potential energy and kinetic energy concepts
  • Knowledge of basic physics principles, including force and motion
  • Experience with material properties relevant to impact testing
NEXT STEPS
  • Research the principles of energy conservation in impact testing
  • Explore methods for measuring impact time in pendulum tests
  • Learn about the dynamics of impact forces and their calculations
  • Investigate alternative methods for estimating impact force without direct measurements
USEFUL FOR

Engineers, materials scientists, and quality control professionals involved in impact testing and material failure analysis will benefit from this discussion.

TL;DR
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.
