Abstract : The NASTRAN computer program is used to solve four simple structural problems. The problems are: (1) a simply-supported beam subjected to lateral loads, (2) a filamentary composite bar under the action of centrifugal forces, (3) a free beam subjected to lateral loads, and (4) the thermal buckling of a simply-supported plate. Input and output data are given for each problem to assist the new NASTRAN user in preparing program input data. The results are compared with solutions obtained by other methods. The example problems disclosed errors in the plotting and thermal-buckling routines of the computer. These have subsequently been corrected. The program was found to have broad capabilities and to offer many user conveniences. (Author)
