For vibration analysis by finite element method, it is necessary to make a detailed mesh design for ensuring the accuracy of solution. However, some practical problems are recognized on dealing with matrices that have a lot of degrees of freedom. Consequently, it is important to make an effot for making a good finite element model for an objective structure to analyze using appropriate number of finite elements. This paper is concerned with the estimation of the minimum number of necessary finite elements for finite element modeling of objective structures before analysis of vibration. To realize it, this paper proposes a way of building up the database system with respect to isoparametric cubic finite elements. In addition, this paper proposes a new type of p-version finite element. The element has only physical nodal point's freedom in spite of much better accuracy for vibration analysis.
