Extension and Application of a Procedure for Damage Assessment of Aerospace Structures.
Abstract
This report documents the extension and application of a computer code for the Automated Design of Damage RESistant Structures (ADDRESS). The program is operable on the VAX-11/780 computer system under the VMS operating system. Extensions to the code over previous work includes the automated selection of damage locations via a sensitivity analysis, linking of design variables for more realistic damage tolerant member sizes, the introduction of standard material sizes in the output design, and the incorporation of a Sturm sequence check for determining frequencies in a given range. Applications are made to typical finite element models of lifting surfaces and to truss structures to validate the code for larger problems. By use of a setup procedure special purpose versions of the code can be made which include user specified upper bounds for key variables such as total number of nodes, elements, and degrees of freedom. Disk storage is the only limiting factor for large problems, rather than program dimension specifications. All large-scale calculations are performed out of core.
