The Eshelby stress tensor, angular momentum tensor and scaling flux in micropolar elasticity
Markus Lazar, Helmut O. K. Kirchner
The (static) energy momentum tensor, angular momentum tensor and scaling flux vector of micropolar elasticity are derived within the framework of Noether's theorem on variational p…
A phase-field model of relaxor ferroelectrics based on random field theory
Shuai Wang, Min Yi, Bai-Xiang Xu
A mechanically coupled phase-field model is proposed for the first time to simulate the peculiar behavior of relaxor ferroelectrics. Based on the random field theory for relaxors,…
Phase-field study of electrochemical reactions at exterior and interior interfaces in Li-Ion battery electrode particles
Ying Zhao, Bai-Xiang Xu, Peter Stein +1
To study the electrochemical reaction on surfaces, phase interfaces, and crack surfaces in the lithium ion battery electrode particles, a phase-field model is developed, which desc…
On microcontinuum field theories: the Eshelby stress tensor and incompatibility conditions
Markus Lazar, Gerard A. Maugin
We investigate linear theories of incompatible micromorphic elasticity, incompatible microstretch elasticity, incompatible micropolar elasticity and the incompatible dilatation the…
Minimum energy path for the nucleation of misfit dislocations in Ge/Si(001) heteroepitaxy
Oleg Trushin, Emile Maras, Alexander Stukowski +4
A possible mechanism for the formation of a 90° misfit dislocation at the Ge/Si(001) interface through homogeneous nucleation is identified from atomic scale calculations where a m…
Magnetism in tetragonal manganese-rich Heusler compounds
Lukas Wollmann, Stanislav Chadov, Jürgen Kübler +1
A comprehensive study of the total energy of manganese-rich Heusler compounds using density functional theory is presented. Starting from a large set of cubic parent systems, the r…
