Concepts of Research

At the Institute of Mechanics fundamental and application-oriented research is performed. One of the central points is the numerical simulation of non-linear static and dynamic problems in structural mechanics. In this connection the development of solid elements and of shell elements, adaptive methods, fast solution for parallel computers, algorithms for large deformations, solution to problems of discontinuity with help of numerical time integration as well as the investigations of more complex applications are being accomplished. To the last one belongs the investigations of stability of steel silo shells in case of different bulk material and different loads, pile-drive vibrations, friction and contact, metal-ceramic crowns loaded by the induced temperature during fabrication and implants in human jaws. The central point of the activities is the connection between the mathematical analysis and carefully chosen experiments, which can be mostly carried out in the laboratories of the Institute.
