Comparison of discontinuous damage models of Mullins-type

Ricker, Alexander; Kröger, Nils Hendrik; Wriggers, Peter (Heidelberg [u.a.] : Springer, 2021)

The Mullins effect is a characteristic property of filled rubber materials whose accurate and efficient modelling is still a challenging task. Innumerable constitutive models for elastomers are described in the literature. ...
Experimental-numerical evaluation of a new butterfly specimen for fracture characterisation of AHSS in a wide range of stress states

Peshekhodov, Ilya; Jiang, S.; Vucetic, Milan; Bouguecha, Anas; Behrens, Bernd-Arno (Bristol : Institute of Physics Publishing, 2016)

Results of an experimental-numerical evaluation of a new butterfly specimen for fracture characterisation of AHHS sheets in a wide range of stress states are presented. The test on the new butterfly specimen is performed ...
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 ...
