Abstract
STARS (STructural Analysis RoutineS) is primarily an interactive, graphics-oriented, finite-element computer program for analyzing the static, stability, free vibration, and dynamic responses of damped and undamped structures, including rotating systems. The element library consists of one-dimensional (1-D) line elements, two-dimensional (2-D) triangular and quadrilateral shell elements, and three-dimensional (3-D) tetrahedral and hexahedral solid elements. These elements enable the solution of structural problems that include truss, beam, space frame, plane, plate, shell, and solid structures, or any combination thereof. Associated algebraic equations are solved by exploiting inherent matrix sparsity. Zero, finite, and interdependent deflection boundary conditions can be implemented by the program. The associated dynamic response analysis capability provides for initial deformation and velocity inputs, whereas the transient excitation may be either forces or accelerations. An effective in-core or out-of-core solution strategy is automatically employed by the program, depending on the size of the problem. Data input may be at random within a data set, and the program offers certain automatic data-generation features. Input data are formatted as an optimal combination of free and fixed formats. Interactive graphics capabilities, using an Evans and Sutherland, Megatek, or any other suitable display terminal, enable convenient display of nodal deformations, mode shapes, and element stresses. The program, developed in modular form for easy modification, is written in FORTRAN for the VAX 11 computer, although earlier development was accomplished using a UNIVAC 1100 computer. Continued development of the program is envisaged, but with care exercised to limit its size (the program now consists of fewer than 12,000 programmed instructions). Applications of the program are anticipated in the fields of aerospace, mechanical, and civil engineering, among others.
