Tom Eppes, professor of electrical and computer engineering; Ivana Milanovic, professor of mechanical engineering; and Shiraz Malik, graduate student in the College of Engineering, Technology, and Architecture (CETA), have published an article in the International Journal of Arts and Sciences (IJAS) Vol. 6, No. 3. The IJAS publishes original contributions on all aspects of science from the academic perspective.

The paper, "Vibrational Response of a Gong," presents the results of a three-dimensional finite element analysis of the eigenmodes of an Indonesian gong suspended in air. A model was developed using COMSOL Multiphysics® to identify discrete vibrational modes, known as eigenfrequencies, which constitute the set of amplitude response patterns produced when the gong is abruptly struck by an external force. These frequencies are driven by the physical geometry and material composition of the gong as well as the suspension system. Contour plots of the complex surface deformations as a function of time are examined along with acoustic wave that propagates into the surrounding air.
