Elastic strain fields of dislocation and dislocation networks as derived
by numerical extended FEM (XFEM) and analytical tools
Master Thesis Topic, Microstructure
Tasks:
The strain field by a single dislocation can be calculated based on text-book knowledge, however,
more complex arrangements usually require numerical approaches. Numerical extended finite element methods (XFEM) may serve as a versatile tool to consider highly realistic geometries and full elastic anisotropy (particularly in 2D layered materials or materials with low crystal symmetry or high anisotropy). A detailed knowledge of the resulting strain landscape contributes to a better understanding of the elastic properties and potentially provides the key to drive plastic relaxation pathway.
Objectives:
Creating XFEM cases for single and multiple dislocation arrangements in various crystallographic systems (e.g., isotropic, cubic and trigonal) and compare results to analytical calculations.
Requirements:
Background in semiconductor physics, materials science, or related fields.
Experience in numerical data treatment as e.g. python but not necessarily Finite Element code
