Abstract
The objective of this study is to form two-dimensional structural/mechanical parts under general loading and restraint conditions. The designs created are of minimum weight with the stresses throughout the parts as close to the allowable limit as possible. The study uses a thresholding approach with minimal designer intervention for generating optimal configurations. The process begins with the user creating an initial design which encompasses all the specified loads and restraints. Finite element techniques are employed to discretize the part geometry. Then a set of heuristics are utilized for shape modification, by removing elements from the finite element model. A Bi-Directional Thresholding technique, (BDT) is developed that determines which elements ought to be removed.
