Abstract:

In this articles honeycomb sandwich finite element was'given, including fundamental hypotheses, formula derivation, computer programs and result comparisons. The subroutines for element stiffness matrix and element stress were written in FORTRAN-IV.They have convenient interfaces and could be easily put into other structural analysis programs.To verify the validation of the programs, we analysed the same structure with both analytic method and MSC/NASTRAN.The results showed that there were few differences.This demonstrated that the honeycomb sandwich finite element was quite useful in structural analysis.

Key words: honeycomb sandwich, structures, finite element
