MDSFP: A Computer Program for Elastic Solution of Three Dimensional Structures by the Finite Element Method (LWBR Development Program)

摘要

MDSFP solves linear elastic, small deflection, three dimensional structures by the finite element method. The idealized model may consist of a mixture of beam, plate, and shell elements connected at node points. Structure loadings are represented by point or distributed loads, temperature distribution, and support displacements. Stresses are calculated from elastic strains which are calculated from nodal displacements. The program was originally written at the Denver Division of Martin-Marietta Corp. It was extensively modified by Bettis to perform elastic analyses of the stresses in various LWBR core structural components resulting from temperature and hydraulic pressure differences.
