Paper Title:
Numerical Simulation Method of Heat-Resistant Hetergeneous Graded Ceramics Structure on Vehicle
  Abstract

From macroscopic view, major structure characteristic of ceramics-metals FGM lies in the fact that every Graded layer is composed of ceramics and metals of different volume component ratio, with their component, structure form or substance parameter presenting Graded change. During temperature rising and dropping, thermal stress will be produced between macroscopic Graded layers and thermal substance mismatch of meso-scopic reinforce phase and matrix within every Graded layer will produce monolayer thermal stress, leading to the failure of overall materials. Because FGM differs obviously in organization states along Graded direction from perpendicular direction, Graded structure shows the distribution features of macroscopic nonhomogeneities, anisotropy and meso-scopic mechanical continuity. Recent related studies mainly adopt FGM equivalent method, particle interface crack theory, uniform theory and effective performance forecasting.
