Structural Optimization via Steepest Descent and Interactive Computation
-
Description
-
In this paper a hybrid method of optimal structural design is developed and applied, using a steepest descent optimization technique in an interactive mode of computing. A method of computing design sensitivity is developed as part of a steepest descent optimization method. A technique is presented for utilization of this data by an experienced designer, interacting with the iterative computer algorithm. The designer is allowed to alter the structural configuration to seek a global, rather than just a local, optimum. Two examples are solved with a number of loading conditions and design constraints to illustrate the flexibility of the technique. Results for these problems are of interest in their own right.

In this paper a hybrid method of optimal structural design is developed and applied, using a steepest descent optimization technique in an interactive mode of computing. A method of computing design sensitivity is developed as part of a steepest descent optimization method. A technique is presented for utilization of this data by an experienced designer, interacting with the iterative computer algorithm. The designer is allowed to alter the structural configuration to seek a global, rather than just a local, optimum. Two examples are solved with a number of loading conditions and design constraints to illustrate the flexibility of the technique. Results for these problems are of interest in their own right.
