Piezoelectric Finite Elements for NASTRAN.

reportActive / Technical Report | Accession Number: ADA082965 | Open PDF

Abstract:

The NASTRAN structural analysis program has been modified so that its TRAPAX and TRIAAX finite elements may handle piezoelectric material properties. These elements are solid, axisymmetric ring elements capable of handling non-axisymmetric loads. The natural frequencies of a piezoelectric hollow cylinder and a piezoelectric disk with electroded surfaces were computed with this modified version of NASTRAM and were found to be in excellent agreement with experimental and other numerical results.
