Stacuss 1: a Discrete-Element Program for The Static Analysis of Single-Layer Curved Stiffened Shells Subjected to Mechanical and Thermal Loads

摘要

A computer code STACUSS 1 for the small-deflection, linear-elastic, static, finite-element analysis of 'thin shells of revolution' having structural and/or material asymmetries has been developed. The code utilizes recently-developed stiffness analyses for doubly-curved quadrilateral and conical triangular shell elements, and straight and curved stiffener elements. Isotropic and/or skew planar orthotropic temperature-independent material properties are accommodated. Mechanical and thermal loadings are taken into account. Also included in the code are (1) automatic mesh generation and plotting and (2) both in-core and out-of-core solution capabilities. (Author)
