Universal behavior in fragmenting brittle, isotropic solids across material properties
Joel T. Clemmer, Mark O. Robbins
A bonded particle model is used to explore how variations in the material properties of brittle, isotropic solids affect critical behavior in fragmentation. To control material pro…
Probing the nonequilibrium dynamics of stress, orientation and entanglements in polymer melts with orthogonal interrupted shear simulations
Marco Aurelio Galvani Cunha, Peter D. Olmsted, Mark O. Robbins
Both entangled and unentangled polymer melts exhibit stress overshoots when subject to shearing flow. The size of the overshoot depends on the applied shear rate and is related to…
From molecular to multi-asperity contacts: how roughness bridges the friction scale gap
Lucas Frérot, Alexia Crespo, Jaafar A. El-Awady +3
While friction stems from the fundamental interactions between atoms at a contact interface, its best descriptions at the macroscopic scale remain phenomenological. The so called "…
Criticality in sheared, disordered solids. II. Correlations in avalanche dynamics
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Disordered solids respond to quasistatic shear with intermittent avalanches of plastic activity, an example of the crackling noise observed in many nonequilibrium critical systems.…
Criticality in sheared, disordered solids. I. Rate effects in stress and diffusion
Joel T. Clemmer, K. Michael Salerno, Mark O. Robbins
Rate-effects in sheared disordered solids are studied using molecular dynamics simulations of binary Lennard-Jones glasses in two and three dimensions. In the quasistatic (QS) regi…
Effect of flow-induced molecular alignment on welding and strength of polymer interfaces
Marco Aurelio Galvani Cunha, Mark O. Robbins
Structures formed by fused filament fabrication are often substantially weaker than those made with conventional techniques, and fail at the welds between successive layers. One fa…
