 note = {We present a practical method of numerical analysis for optimization problems of domains in which natural vibration problems of linear elastic bodies are defined. In this paper,we apply the traction method that was proposed as a solution to the domain optimization problems to elliptic boundary value problems. The treated problems are those which determine the domain that maximizes a specified vibration eigen value,which is defined by the squared natural frequency,and that moves several specified vibration eigen values in a specified direction.Using the Lagrange multiplier method,we obtain the shape gradient functions for these domain optimization problems from the optimality criteria. We show the successful resolution of the problems of beamlike plates clamped at one end and at both ends.},
