Additions to the Isoparametric Elements and Rigid Format 14 Extensions in Navy-NASTRAN.
Abstract
A modified version of NASTRAN Level 15.1 was previously developed at DTNSRDC and designated Navy-NASTRAN. It included such features as isoparametric finite elements, fully stressed design, and a thermal transient-structural static analysis, among others. This report documents four new capabilities: principal stresses for the isoparametric elements, differential stiffness for the isoparametric elements for use in buckling and static analysis with differential stiffness analyses, a method to include differential stiffness effects with the static analyses following a thermal transient analysis, and a method to execute a structural transient analysis following a thermal transient analysis. These new capabilities are available on CDC 6000 and Univac 1100 computers. (Author)
