The role of weakest links and system size scaling in multiscale modeling of stochastic plasticity
Péter Dusán Ispánovity, Dániel Tüzes, Péter Szabó +2
Plastic deformation of crystalline and amorphous matter often involves intermittent local strain burst events. To understand the physical background of the phenomenon a minimal sto…
Disorder is good for you: The influence of local disorder on strain localization and ductility of strain softening materials
Dániel Tüzes, Michael Zaiser, Péter Dusán Ispánovity
We formulate a generic concept model for the deformation of a locally disordered, macroscopically homogeneous material which undergoes irreversible strain softening during plastic…
Size and Disorder Effects in Elasticity of Cellular Structures: From Discrete Models to Continuum Representations
Stefan Liebenstein, Stefan Sandfeld, Michael Zaiser
Open cellular solids usually possess random microstructures that may contain a characteristic length scale, such as the cell size. This gives rise to size dependent mechanical prop…
Dislocation patterning in a 2D continuum theory of dislocations
Istvan Groma, Michael Zaiser, Peter Dusan Ispanovity
Understanding the spontaneous emergence of dislocation patterns during plastic deformation is a long standing challenge in dislocation theory. During the past decades several pheno…
