With ANSYS,a finit element analysis software and the rigidity matrix arithmetic,the stress analysis and the mode analysis of a MEMS high g accelerometer structure are performed.

Based upon the principle of the stiffness matrix method, a general method is offered to seek the two dimensional fundamental solutions to layered elastic media,by which semi-analytical method can be set up to finite layered structure analysis.

A modified stiffness matrix method for analysing system of complicated elastic foundation beam;

Combining basic Surface Acoustic Wave (SAW) theory with reported recursive stiffness matrix method, this paper deduces an effective permittitivity mathematical model of Rayleigh wave based on ZnO/Diamond/Si-layered structure through separating the Rayleigh wave from SAW.
