Mechanics of a Model Frictional Knitted Fabric
Laura Michel, Antoine Faulconnier, Audrey Steinberger +2
We present a study of the shapes and mechanical properties of a knitted loop made of elastic and frictional yarns. First, for non-frictional yarns, we investigate how the elastic e…
Laddering of a knitted fabric: a topology-induced failure
Antoine Faulconnier, Laura Michel, Mokhtar Adda-Bedia +2
Laddering is the propagation of a topological defect in an everyday-life material: weft knitted fabrics, following a broken thread or a dropped stitch. What is a minor frustration…
Frictional sliding strength of knotted and capstan configurations along the axis of a cylinder
Javier Sabater, Ji-Sung Park, Jérôme Crassous +2
We investigate the sliding strength of thin filaments in frictional contact with a translating cylinder, perpendicular to the filaments' axes, in knotted (clove hitch) and unknotte…
Self-locking and Stability of the Bowline Knot
Bastien F. G. Aymon, Fani Derveni, Michael Gomez +2
We investigate the self-locking of the bowline knot through numerical simulations, experiments, and theoretical analysis. Specifically, we perform two complementary types of simula…
Metastability of a periodic network of threads: what are the shapes of a knitted fabric ?
Jérôme Crassous, Samuel Poincloux, Audrey Steinberger
Knitted fabrics are metamaterials with remarkable mechanical properties, such as extreme deformability and multiple history-dependent rest shapes. This letter shows that those prop…
Aftershocks as a time independant phenomenon
A. Mathey, J. Crassous, D. Marsan +2
Sequences of aftershocks following Omori's empirical law are observed after most major earthquakes, as well as in laboratory-scale fault-mimicking experiments. Nevertheless, the or…
