Multiscale Elasto-dynamics


Now a days, considerable progress is being made in the design of composite materials which can exhibit properties that are not found in naturally occurring materials. Numerical homogenization techniques are used in order to find effective properties of periodic microstructures at the macro-scale. In conventional homogenization methods, the material properties are averaged over a repeating Representative Volume Element (RVE) in order to calculate those effective properties. But in the case of elastodynamics, uniform volume averaging can lead to a loss of phase information which is necessary to accurately describe the elastodynamic material at the macro-scale. Such limitations can be overcome by transferring the microscale information to the fourier space and then projecting the frequency modes to a reduced space composing a few selected Floquet-Bloch eigenmodes, thereby reducing the degrees of freedom at the macro-scale. The homogenized parameters can then be utilized in a material optimization
setting, thus optimizing the dynamic properties of the structure.

Topology optimization and 3D Printing: assistance in project-related work

The project’s focus is the development of a new multi-axis additive manufacturing technology with continuous fibers. Our contribution is the design of optimized components with applications in the aircraft industry. One current challenge is the translation of these designs into actual fibers and printing sequences for the manufacturer.
For this purpose, we are looking for assistance to acquire
existing approaches from literature for solving this problem.
