Requirements and recommendations:
Requirements for this course are basics in mathematics and mechanics, as they are given by the foundation courses of mechanical engineering.
The parallel participation at the exercise "Smart Materials" is required.
Aim of the event:
This course is an introduction to the wide field of so called 'new materials'. These modern materials do not only give a construction the needed mechanical foothold by their structural characteristics, but additionally take over sensor and actor functions. Also, their mechanical characteristics (e.g. Young's modulus or viscosity) can be affected by electrical, magnetical or thermical fields in a well directed manner. Key aspects of the course are the demonstration of physical basics and the mathematical description of different materials and effects. Technical applications are presented by selected examples. The course is supplemented by practical trainings.
Target group:
This course is directed to students of mechanical engineering, industrial engineering, techno-mathematics, information science in engineering and physics.
