Discrete Direct Sensititivity Analysis Method of Bending Element with Six Degree of Freedom
Author
Abstract
This paper is about discrete sensitivity analysis. A triangular bending element with constant moment and six degrees of freedom is used. The required derivatives for sensitivity analysis are calculated explicitly. These formulations, finite element method and sequential linear programming are utilized to find shape optimization of plate bending structures. The numerical examples, which show the ability of the derivatives, are presented.
