How to take into consideration shear waves

Please login with a confirmed email address before reporting spam

Hello, Please help me.

In acoustics module, how do we specify that specific domains are solid. In order to take into consideration the shear waves. I am using pressure acoustics, frequency domain physics, like the tutorial ''ultrasound induced heating''.

Thanks in advance,

Nesma

Hi, Nesma El Sayed This problem has also been bothering me. I have not observed shear waves in the time domain signals I extracted. If you know how to solve this problem, wish you share it with me.

Thank you!

Hi Dan,

I figured out that you need to couple solid mechanics with pressure acoustics and use the built-in multiphysics feature acoustic-structure. Then you will see how the pressure wave will transform into elastic wave in the solid domain. I have done this study in the frequency domain.

I don't know if this help you but tell me if you have other questions
