On the modeling of deformation induced anisotropy of pearlitic steel
- 2010

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- A micromechanically based plasticity model for modeling of anisotropy in pearlitic steel is investigated. The model was proposed in Johansson and Ekh~[1] and takes into account large strains as well as deformation induced anisotropy. The initially randomly oriented cementite lamellae in the pearlitic steel will tend to align with the deformation which causes a development of anisotropy.

Investigation of Screech in Supersonic Jets Using Modal Decomposition
- 2014
-

-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- The present study attempts to identify the eigenmodes that are associated with the screech mechanism by means of Dynamic Mode Decomposition (DMD) and a method based on the Arnoldi eigenvalue algorithm, respectively.
