Basis for Element Interchangeability in Finite Element Programs

Title
Basis for Element Interchangeability in Finite Element Programs
Description
The concept of characteristic matrices of any finite element for elastostatic analysis is presented. To demonstrate the concept the characteristic matrices of a simple beam element are derived in the Appendix. This approach permits complete interchangeability of different types of elements between independently developed analysis programs irrespective of the analysis method or basic element assumption. The analogy between element derivation procedures and the equality of principal matrices are developed. A wide spread adoption of this concept would have far reaching implications in, facilitating communications, exchanging of new developments, and speed-up practical applications in the field of finite elements.
