A Finite Element Method for Optimum Beam Design.
Abstract
A finite element method for structural optimization of a prismatic beam of a homogeneous, isotropic material is developed. The beam has a rectangular cross-section of constant fixed height, a fixed length, and a fixed volume. Structural optimum is defined as that shape which allows a maximum load within the elastic range. A computer program is developed to solve the resulting system of equations and various example problems are solved. Comparison is made with exact optimum beam designs where possible. The finite element model is able to solve problems with any boundary conditions and types of loading that are consistent with the number of elements selected. (Author)
