Optimum design of plastic bar structures for shakedown and dynamic loading
In this paper, two different problems of optimum design are presented. The first problem is the optimum design of elastic-perfectly plastic bar structures (frames and trusses) under variable (shakedown) loading while the second one is the optimum design of rigid-perfectly plastic bar structures under dynamic pressure with specified displacement constraints. In both cases, nonlinear objective functions are used. The proposed two methods can be formulated as a nonlinear programming problem and their solutions are based on the same iterative procedure. The applications are illustrated by numerical examples.
