Relation of Sonic Velocity and Density
Relation of Sonic Velocity and Density
(OP)
I am looking to calculate the density of a material, using an ultrasonic thickness gauge. Through physical measurement of the part I can use the gaue to obtain the sonic velosity of the material. However I am in need of the formula that relates the sonic velosity of the ceramic to the desity. If any of you are falmiliar with this relationship, I would appreciate the help!

L = (E/rho)^0.5
where E = Young's modulus and rho = mass density. Solving for the density,
rho = E/(L^2)
If you look up the modulus of elasticity, then you will be able to calculate the density of this material using the above equation. Good luck!
