What are the equations to measure attenuation of stress wave

Click For Summary

Discussion Overview

The discussion revolves around the equations necessary to measure the attenuation, frequency, and amplitude of stress wave propagation in a metal rod or plate immersed in water or another fluid. Participants explore the context of generating vibrations in the rod and the resulting wave behavior in the surrounding fluid.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant asks for specific equations related to measuring attenuation, frequency, and amplitude of stress waves in a metal rod immersed in fluid.
  • Another participant notes that the equations will depend on the measurement method and requests more details for a precise response.
  • A participant reiterates the original question, providing context about a tank filled with water and the generation of waves from vibrations applied to the rod.
  • One participant challenges the clarity of the inquiry, emphasizing the need for measurements to determine amplitude and frequency, which depend on the method of vibration production.
  • This participant also states that attenuation is material-dependent and suggests measuring wave amplitude at various points along the rod to obtain relevant data.

Areas of Agreement / Disagreement

Participants do not reach a consensus on specific equations, and multiple competing views regarding the measurement methods and dependencies remain evident throughout the discussion.

Contextual Notes

The discussion highlights limitations related to the lack of specific measurement methods and the dependence on material properties for attenuation calculations. There are unresolved aspects regarding the precise equations needed for the inquiry.

what are the equations to measure attenuation, frequency, amplitude of a stress wave propagation of metal rod or plate which is immersed in water or fluid?

The equations will depend on the method used to measure these quantities.
You need to give more details in order to get more detailed answers.

consider, there is tank filled with water and metal rod immersed into it. when we give vibrations to that rod. due to these waves are generated into water. these waves have some attenuation, frequency, amplitude. to calculate these i want equations related these...
 
You are just repeating what you said in the OP.
You need to do some measurements in order to get these quantities. The amplitude and frequency will depend on how do you produce these vibrations. There is no way to calculate them from nothing, just on the base of some magic equations.

The attenuation will depend on the material. If you want to measure it, you will need again to do some measurements. You could measure the amplitue of the wave at different points along the rod.
 
thanks
