Research interests:   

One of the main goals of mechanics is the description and the prediction of the motion of mechanical devices, machines and mechanical processes. To meet this aim, abstract mechanical theories are formulated, thereby applying concepts from mathematical science. In such a determinism, a strict separation between reality and mathematical abstraction, called the model, has to be considered. The modeling process, being the procedure of the mathematical abstraction, is an interaction between the choice of the assumed mathematical structure and the description of observations in the real world within this mathematical framework. Hence, a mechanical theory can be developed on different levels of mathematical abstraction. The higher the level of mathematical abstraction, the less mathematical objects are involved and the more general a mechanical theory is.

Computational mechanics

  • Efficient numerical analysis of pantographic structures applying higher gradient continuum theories
  • Numerical schemes which respect the underlying geometric properties of mechanical systems
  • Development of nonlinear finite element formulations for nonlinear beam theories
 

Geometric and variational mechanics

  • The notion of stress in a variational formulation of continuum mechanics
  • Intrinsic differential geometric description of the fundamental principles of continuum mechanics
  • Geometric formulation of analytical dynamics with non-holonomic constraints on metric-affine spaces
