Shear shocks in fragile networks
Stephan Ulrich, Nitin Upadhyaya, Bas van Opheusden +1
A minimal model for studying the mechanical properties of amorphous solids is a disordered network of point masses connected by unbreakable springs. At a critical value of its mean…
Soliton attenuation and emergent hydrodynamics in fragile matter
N. Upadhyaya, L. R. Gomez, V. Vitelli
Disordered packings of soft grains are fragile mechanical systems that loose rigidity upon lowering the external pressure towards zero. At zero pressure, we find that any infinites…
Solitons and thermal fluctuations in strongly nonlinear solids
N. Upadhyaya, A. M. Turner, V. Vitelli
We study a chain of anharmonic springs with tunable power law interactions as a minimal model to explore the propagation of strongly non-linear solitary wave excitations in a backg…
Transmission and reflection of strongly nonlinear solitary waves at granular interfaces
A. M. Tichler, L. R. Gomez, N. Upadhyaya +3
The interaction of a solitary wave front with an interface formed by two strongly-nonlinear non-cohesive granular lattices displays rich behaviour, characterized by the breakdown o…
