文摘

The subject matter of the article is a fixed circular multi-layer plate and its reaction to the axially symmetrical force (direct stress) affecting its front face. The force itself is an arbitrary time and radial coordinate function. The authors apply the method of finite integral transformation (based on the theory of electroelasticity in a three-dimentional model) to develop a new closed solution. The improvement of this new solution lies in the fact that boundary conditions for cylinder and front faces of a multi-layer plate here are completely fulfilled when compared with the data obtained in previous research. The achieved ratio design allows to further analyze this multi-layer plate fluctuations frequency content as well as to analyze changing characteristics of its stress-strain behaviour and their dependence on different layers stress-strain properties.
