Abstract

In this study, 3 kinds of holes (square, circular and elliptic holes) are attempted on a cantilever to reduce the weight by 30%. Maximum Von-Mises stresses of cantilever plate with 3 kinds of holes are investigated. For the elliptic holes, a shape optimization is attempted to fad the optimum angle of axis by rotating the axis by $10^{\circ}\; from\; 50^{\circ}\; to\; 120^{\circ}\;$ From the results, it is known that the maximum stress is decreased to 0.868 MPa by rotation of the axis of elliptic hole and 0.26 MPa is decreased compared with the maximum stress occurred on the circular hole.
