Abstract
Finite Element Method(FEM) is the essential tools for analyzing structural and vibration problem. But common commercial program is high-priced and the usage is not easy. Hereby the authors developed FEM program by using Matlab, whose usage is very simple and whose performance is very high. For the convenience of use and calculating efficiency Component Mode Synthesis Method is adopted, which divides a structure by some sub-structures for easy handling, analyzes them by parts and analyzes the structure with encompassing Degrees of Freedom(DOF). And encompassed DOF could be restored to full DOF. To confirm the accuracy the program was applied to a flat plate, and the results were compared to experiment, and good agreements were achieved. The developed program is going to be opened to public.
