Thawed Matrix method for computing Local Mechanical Properties of Amorphous Solids
Jörg Rottler, Céline Ruscher, Peter Sollich
We present a method for computing locally varying nonlinear mechanical properties in particle simulations of amorphous solids. Plastic rearrangements outside a probed region are su…
Dynamic phase diagram of plastically deformed amorphous solids at finite temperature
Daniel Korchinski, Jörg Rottler
The yielding transition that occurs in amorphous solids under athermal quasistatic deformation has been the subject of many theoretical and computational studies. Here, we extend t…
Avalanches in the athermal quasistatic limit of sheared amorphous solids: an atomistic perspective
Céline Ruscher, Jörg Rottler
We study the statistical properties of the yielding transition in model amorphous solids in the limit of slow, athermal deformation. Plastic flow occurs via alternating phases of e…
Molecular mobility in driven monomeric and polymeric glasses
Joerg Rottler
We show that in monomeric supercooled liquids and glasses that are plastically flowing at a constant shear stress while being deformed with strain rate , the microscopic…
Orientation of plastic rearrangements in two-dimensional model glasses under shear
Alexandre Nicolas, Jörg Rottler
The plastic deformation of amorphous solids is mediated by localized shear transformations involving small groups of particles rearranging irreversibly in an elastic background. We…
Correlation between rearrangements and soft modes in polymer glasses during deformation and recovery
Anton Smessaert, Joerg Rottler
We explore the link between soft vibrational modes and local relaxation events in polymer glasses during physical aging, active deformation at constant strain rate, and subsequent…
