Hard challenge with soft materials: Understanding large deformation and fracture behavior
(Budapest University of Technology and Economics, 2013-12)
Rubber has been recognized as an engineering material since the mid 1800s. It is well known that the mechanical behavior of rubber is complicated due to nonlinearity, hyperelasticity and its great sensitivity to the effects ...
Soliton attenuation and emergent hydrodynamics in fragile matter
(American Physical Society, 2014-03-26)
Disordered packings of soft grains are fragile mechanical systems that lose rigidity upon lowering the external pressure toward zero. At zero pressure, we find that any infinitesimal strain impulse propagates initially as ...
Multipeaked polarons in soft potentials
(American Physical Society, 2004-08-10)
We consider a minimal coupled charge/excitation-lattice model capturing a competition between linear polaronic self-trapping and the self-focusing effects of a soft nonlinear on-site potential. The standard singlehumped ...
