An extended Hamilton principle as unifying theory for coupled problems and dissipative microstructure evolution

Junker, Philipp; Balzani, Daniel (Berlin ; Heidelberg : Springer, 2021)

An established strategy for material modeling is provided by energy-based principles such that evolution equations in terms of ordinary differential equations can be derived. However, there exist a variety of material ...
Phenomenological modeling of anisotropy induced by evolution of the dislocation structure on the macroscopic and microscopic scale

Clausmeyer, Till; van den Boogaard, Ton; Noman, Muhammad; Gershteyn, Grygoriy; Scharper, Mirko; Svendsen, Bob; Bargmann, Swantje (Heidelberg : Springer Verlag, 2011)

This work focuses on the modeling of the evolution of anisotropy induced by the development of the dislocation microstructure. A model formulated at the engineering scale in the context of classical metal plasticity and a ...
