Natural Frequency Maximization Using a Flat-top Emboss

Even though embossing is an effective SDM(Structural Dynamics Modification) technique, it is difficult to implement the method in fields owing to its geometric complexity. In this research low flat-top emboss shape, rather than general shape, is considered and a systematic procedure is derived in describing the emboss implementation procedure utilizing the fact that the emboss shape can be fully expressed only if the boundary elements are appropriately given. Best position to maximize natural frequencies is found using the procedure and usefulness of the suggested technique is illustrated.
