Title: Application of design optimization in structural acoustics
Abstract: 
Unwanted sound noise of the structures can harm the human health and the global environment. Therefore, it has been always desirable to reduce the radiated noise from the structures. However, it is a very difficult task to find the optimum design for structural acoustic applications. In fact, due to the nonlinear nature of main objective function in structural acoustics applications, it is very difficult to find the global optimum design where the structure radiates the less amount of noise into the surrounding medium. Indeed, it is needed to use and combine effective optimization and approximation algorithms with advance geometry modification techniques to find a suitable design in this manner. In this talk, the concept of geometry modification will be applied on various structures from shells to sandwich panels and auxetic metamaterials to reduce their noise radiations. This talk is representing the more than 18 years of experience of Dr. Ranjbar in structural acoustics design optimization.
Biography: 
Dr. Mostafa Ranjbar is an expert in multidisciplinary engineering design optimization for structural acoustics and vibroacoustics of mechanical metamaterials. He has a PhD degree in mechanical engineering with a focus on structural acoustics from Technical University of Dresden in Germany. He has more than 18 years of international experiences in the field of noise and vibration control. He is the author of more than 70 scientific publications with extensive international experiences. His background is in computational acoustics; he has developed several numerical multi-domains optimization models to design mechanical metamaterials as optimal cores for minimal acoustic radiation performance in vibrating sandwich and architected structures. Dr Ranjbar has also setup his own vibroacoustics laboratory and supports the development of structures with negative Poisson ratios (auxetic) and other types of lattice structures for wave propagation tailoring and control. He has supervised many undergraduate, MSc and PhD theses in various countries in the field of structural acoustics. Furthermore, he has successfully finished several industrial projects about structural noise reduction with famous international companies. Moreover, he has either chaired or presented several keynote speeches in various famous international conferences about noise and vibration control.
