The Laboratory of Machine Design (MDL) contributes to the education of experts in the field of Mechanical Design. Accomplishments of Ph.D. level students of the laboratory are appreciated by both academia and industry. The mission of MDL is to improve design quality, shorten design time, and enhance design education by developing design tools for innovative product development. The design tools developed include design methodology and computer-aided design software systems. The foundation of this development is the science of design, which provides scientific means for studying design activities. The design tools are used to help companies rapidly develop high quality new products. The active research areas of MDL are nanotechnology, dynamics of rotating machinery, tribology-nanotribology, smart lubricants, active magnetic and hydro magnetic bearings, finite and boundary element methods, artificial intelligence and biomedical field. MDL is under the direction of Professor Nikolaos Anifantis and consists of five faculty members and 6 Ph.D students. MDL collaborates with a number of international research groups among which the Network on neutron Techniques standardization for structural integrity (NET).
