Dear Sir
Nice to meet you, I’m very honor can ask and get the answer from you about RUS discussion.
I’ve read your paper “Resonant Ultrasound Spectroscopy to Measure Tensile Strength and Rockwell C Hardness”, Materials Evaluation, Vol. 56, May 1998, pp. 600-605.
This topic are become my final project for graduating mechanical engineering in ITS Surabaya, Indonesia. I try to apply your paper by making software and interface by myself, however I know there are DRS Software and Q9000 for useful application. (This is very expensive for me to use DRS Q9000 and Modulus I, but I’m very thank you if you don’t mine to give it………)
The point is not on this software and interface, but how to understand this method (RUS) could help to find materials measurement (Tensile, Hardness, Defect, and could be possible material composition structure?).
Here is the problem.
I can solve the frequency equation, but I meet difficulty to correlate frequency to tensile strength and hardness. Where is the Q come from? What are must be include the equation? (ex: elastic constant, dimension geometry, density, or etc?)
As I read on your paper, for example 173.43 kHz result 1223.69 MPa (177.48 klb/in.2). It is easy to find the frequency (173.43 kHz), from my software it is work done and show 173.43 kHz, then I stop right here. How I get 1223.69 value for Tensile strength?
Please give me some explanation and the equation to find tensile from frequency that I’ve got already.
This is also for Rockwell C Hardness case.
I need your response ASAP, I’m sorry, because I have the limit time (on 10 May 2000), I have to presentation in front of the team.
Thank you for your helping, I’ll wait your asnwer please.
Sincerely yours,
Gunawan RM
