Acoustoelastic effect [ultrasonic wave propagation]

Hi,
I am using COMSOL 5.5.
I would like to know if (Physics: Elastic Waves, Time Explicit ) is able to simulate the acoustoelastic effect "change in the aoustic wave velocity due to stress" of an ultrasonic wave propagating in (Material: Structural Steel).
If not, I was thinking to use (Physics: Solid Mechanics) with Hyperelastic material> Murnaghan Model . Then, creating two steps simulation:
Step1: stationary, in which a static load is applied on the structure. Step2: Time-Dependent, in which a transducer sends an ultrasonic wave.
The solution of Step1 is used as initial state for Step2.
would this work ?
Thank you.
