Though we had studied the structural optimization technique using the shell element model until now, the optimization using the solid element model was not researched. Therefore, the growth-strain method carried out by Azegami etc, was applied to stress reduction on the roots of wing and the axis of The Miniature Impeller. At first, stress analysis is performed, and the second, thermal deformation analysis is performed by the fictitious temperature with proportional to absolute value of stress. Constraint are decided in each analysis and performed. Stress reduction is attained by the two repetition calculation. Because it was also applied to the simple cantilever beam model, it is united and reported.
