摘要：
We use radiative transfer equations to describe the high-frequency vibrations of randomly heterogeneous plates. The diffusive regime is depicted both numerically and analytically from this model. Numerical simulations are based on the Monte-Carlo method, whereas the analytical model is obtained by an asymptotic analysis. The objectives are to improve the understanding of high-frequency vibrations of complex industrial structures.
