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
