QUAD4 Seminar. Revision

Abstract

NASTRAN (NASA STRuctural ANalysis Program) is the most widely used general purpose structural analysis program in the world. This program was originally developed in the mid-sixties, and the first version was released in 1968. The program developed and sponsored by the National Aeronautics and Space Administration (NASA). This development in the form of enhancements and maintenance was continued until 2972 as a single Government version under the sponsorship of NASA. Since then the Government version under the sponsorship of NASA. Since then the Government version is being developed as COSMIC-NASTRAN, while a commercial version is being marketed by McNeal and Swendler Corporation (MSC) as MSC-NASTRAN. Even through the basic structure of these two versions remains the same, there are significant differences in capabilities and efficiencies. Around 1980 the MSC introduced a new plate bending element called the QUAD4 to its element library. It is one of the most versatile plate bending elements, even though its theoretical basis is somewhat controversial
