I have a situation in mind, where at a number of points there is placed a material that positively strains in response to a stimuli, like pictured below,
This is to produce a Rayleigh or surface acoustic wave (SAW) that propagates along the surface. Using the material properties and strains of actuation material, I can work out the stress placed along the substrate layer.
However, I am not sure how to go about moving this forward into a calculation of energy of the wave produced. Which is what I am interested in finding out.
I have come across how the energy is proportional to the amplitude of the wave squared. I am not sure how or if I could work out an amplitude of this and what other factors I would need to consider.
Any suggestions as to how I might approach this, would be appreciated.
