A General Purpose Three Dimensional Stress Analysis Program,

Abstract

A computerized solution for three dimensional stress analysis was developed. The solution was based on the finite element technique employing twenty and thirty-two nodal point three dimensional isoparametric elements. The solution is applicable to linear elastic structures composed of homogeneous and isotropic materials subjected to static loading under constant temperature. Deformed states are restricted to small displacements and displacement gradients. The program is coded in standard FORTRAN IV and is machine independent except for one subroutine which may be adjusted to specific installations. Independence of core space requirements is achieved by use of direct access storage facilities. (Author)
