A question on boundary condition
A question on boundary condition
(OP)
I am analyzing the ultrasonic sound pressure in a pipe. As mentioned in many references, when the metal pipe has a enough thick wall, it can be looked as a rigid boundary! Any boby can tell me how thick is thick enough!?





RE: A question on boundary condition
as far as i know, if u r considering the pipe wall as a rigid body, what ever the thickness value u will give does not matter. But how ever, depending on the diameter of the pipe u can find the DIN standard thickness for the pipe..and depend on the value u can assign the thickness..

i have carried out a experiment. A acrylic pipe, is not a resonance dimension . and i think it is reasonably solid . but the distribution of sound pressure in the pipe is in agreement with the theoretical value of soft boundary!
