Modeling impact-echo on Comsol

Please login with a confirmed email address before reporting spam


my research project is based on modeling the impact-echo method in order to analyze frequency responses of the structure. I work on post-tensioned concrete beam with ungrouted duct and I want to test this structure to determine the possibilities of impact-echo to detect voids inside the duct. So my question is on the choice of the module in Comsol. I chose pressure acoustic module and I want to know if I’m right because this is normally for fluids or gaz. I simulate the impact by parametric solver. I inject a series of frequency which belong to a specter. then I plot the results in Matlab program.

Thank you for your help
