- •
Finite element modeling of ultrasound propagation in aluminum foams was performed.
- •
The models included microstructures of water-saturated aluminum foams.
- •
Ultrasonic attenuation and velocity in aluminum foams were simulated.
- •
To verify the simulation results, corresponding experiments were performed.
- •
The simulated parameters were in good agreement with the experimental results.
