| Abstract: | This paper presents a generalized optimality criterion method for structural optimization. Extensions are made respectively to Chen's method for optimality criterion and Heo's method for substructural sensitivity synthesis to allow the treatment of multiple eigenvalue case,and Czyz's approach is improved by means of generalized variation of the design vector. |
