The Fokker-Planck (FP) equation is frequently used when the response of the dynamic system subjected to additive and/or multiplicative ramdom noises is investiagted. It provides the probability density function (PDF) representing the key information for further study of the dynamic system. Various analytic and semi-analytic solution methods have been developed for various systems to obtain results requested. However numerical approaches offer a powerful alternative. In particular the Finite Element Method (FEM) seems to be very effective. A couple of single dynamic linear/non-linear systems under additive and multiplicative random excitations are discussed using FEM as a solution tool of the FP equation. and Obsahuje seznam literatury
