Dislocations in the elastic fields of randomly distributed defects
Ronghai Wu, Michael Zaiser
In recent years, the behavior of dislocations in random solid solutions has received renewed interest, and several models have been discussed where random alloys are treated as eff…
Multiscale modeling of dislocations: Combining peridynamics with gradient elasticity
Jonas Ritter, Michael Zaiser
Modeling dislocations is an inherently multiscale problem as one needs to simultaneously describe the high stress fields near the dislocation cores, which depend on atomistic lengt…
Failure precursors and failure mechanisms in hierarchically patterned paper sheets in tensile and creep loading
Mahshid Pournajar, Tero Mäkinen, Seyyed Ahmad Hosseini +3
Quasi-brittle materials endowed with (statistically) self-similar hierarcical microstructures show distinct failure patterns that deviate from the standard scenario of damage accum…
Effects of disorder on deformation and failure of brittle porous materials
Jonas Ritter, Shucheta Shegufta, Michael Zaiser
The mechanical behavior of porous materials depends strongly on porosity and pore geometry, but also on morphological parameters characterizing the spatial arrangement of pores. He…
An energetically consistent surface correction method for bond-based peridynamics
Jonas Ritter, Shucheta Shegufta, Paul Steinmann +1
A novel surface correction method is proposed for bond based peridynamics which ensures energy consistency with a classical reference body for general affine deformations. This met…
Predicting Creep Failure by Machine Learning -- Which Features Matter?
Stefan Hiemer, Paolo Moretti, Stefano Zapperi +1
Spatial and temporal features are studied with respect to their predictive value for failure time prediction in subcritical failure with machine learning (ML). Data are generated f…
