Abstract
Ulrasound transducers with phased arrays are used in multiple areas, including medical and technical applications. The numerical modeling of the composite ultrasound requires high spatial and temporal resolution with a full viscoelastic anisotropic material model. The grid-characteristic method that can provide it is demanding in terms of calculation time. A problem of optimal adjusting of the phased array requires a fast and effective numerical method. The retracing method for acoustics that is used for ultrasound and seismic problems, improved with a wavefront construction method was implemented. A technique of modeling the ultrasound of composites with good accuracy and in a reasonable time is proposed.
