Abstract : ELAD is a computer program designed to determine elastic deformations, stresses, strains, and principal values of stresses within axisymmetric solid structures of arbitrary shape subjected to axisymmetric or unsymmetric pressure, concentrated loads, and temperatures. All possible combinations of boundary conditions are permitted consistent with the theory of elasticity. As a special optional feature the ELAD program handles the detailed stress analysis of hemispherical or ellipsoidal thick-walled dome structures due to a prescribed value of externally applied pressure. When considering specific dome-geometry configurations, the program accepts simple descriptive dimensions of the dome and automatically generates all the geometry and material data with which to perform the deflection and stress analysis. In addition, a capability is provided for convenient input of specialized axisymmetric nonuniform pressure distribution when using the dome geometry option. If the dome features are not desired, one may alternatively input the geometry and loading conditions for an arbitrary solid of revolution and unsymmetrical pressure (concentrated load or temperature) configurations. If desired, a plot (CRT) of the gridwork mesh of continuum elements used to describe the body may be obtained. A linear but orthotropic elastic stress-strain relationship is assumed throughout. The program manual is divided into four distinct topics. These include theory, general description of the computer program, detailed use of the program, and sample case studies. (Author)
