This research paper presents an investigation into the modeling of ultrasonic wave propagation within composite materials, employing advanced grid-characteristic methods and Chimera grids. The study utilizes an isotropic linear elastic medium as a fundamental model to describe the dynamics of individual structures in composite materials. To solve the problems, the grid-characteristic method was used on both structured rectangular and curvilinear grids. The methodology introduces Chimera grids within a single uniform background mesh, allowing for independent solutions in each grid at subsequent time steps. This approach not only enhances the precision of describing wave front behavior at material contact boundaries but also streamlines computational processes through parallelization, showcasing exceptional scalability. The results demonstrate significant advancements in understanding ultrasonic wave dynamics within composite materials, with implications for refining simulation techniques in the future.
