Velocity-strengthening friction significantly affects interfacial dynamics, strength and dissipation.

Scientific reports

Bar-Sinai Y, Spatschek R, Brener EA, Bouchbinder E.
PMID: 25598161
Sci Rep. 2015 Jan 19;5:7841. doi: 10.1038/srep07841.

Frictional interfaces abound in natural and man-made systems, yet their dynamics are not well-understood. Recent extensive experimental data have revealed that velocity-strengthening friction, where the steady-state frictional resistance increases with sliding velocity over some range, is a generic feature...

Angular transport in a nonperiodic Chirikov-Taylor map.

Physical review. E, Statistical, nonlinear, and soft matter physics

Lesnik D, Spatschek KH.
PMID: 11736052
Phys Rev E Stat Nonlin Soft Matter Phys. 2001 Nov;64(5):056205. doi: 10.1103/PhysRevE.64.056205. Epub 2001 Oct 15.

Transport in angular direction is considered for a nonperiodic Chirikov-Taylor (standard) map. In the limit of large stochasticity parameter, depending on the boundary conditions of the action variable, either superdiffusive of diffusive behavior is found. In both cases characteristic...

Chirped solitons as attractors for short light pulses.

Physical review. E, Statistical, nonlinear, and soft matter physics

Neuer M, Spatschek KH, Li Z.
PMID: 15600777
Phys Rev E Stat Nonlin Soft Matter Phys. 2004 Nov;70(5):056605. doi: 10.1103/PhysRevE.70.056605. Epub 2004 Nov 15.

Nonlinear chirped pulse solutions are shown to exist as stable attractors for short light pulses in driven and damped systems. The attractors are determined for systems of different complexity, from simple gain and damping modelings up to the inclusion...

Influence of strain on the kinetics of phase transitions in solids.

Physical review. E, Statistical, nonlinear, and soft matter physics

Brener EA, Marchenko VI, Spatschek R.
PMID: 17500904
Phys Rev E Stat Nonlin Soft Matter Phys. 2007 Apr;75(4):041604. doi: 10.1103/PhysRevE.75.041604. Epub 2007 Apr 16.

We consider a sharp interface kinetic model of phase transitions accompanied by elastic strain, together with its phase-field realization. Quantitative results for the steady-state growth of a new phase in a strip geometry are obtained, and different pattern formation...

Crack propagation as a free boundary problem.

Physical review letters

Pilipenko D, Spatschek R, Brener EA, Müller-Krumbhaar H.
PMID: 17358486
Phys Rev Lett. 2007 Jan 05;98(1):015503. doi: 10.1103/PhysRevLett.98.015503. Epub 2007 Jan 05.

A sharp interface model of crack propagation as a phase transition process is discussed. We develop a multipole expansion technique to solve this free boundary problem numerically. We obtain steady state solutions with a self-consistently selected propagation velocity and...

Instabilities at frictional interfaces: creep patches, nucleation, and rupture fronts.

Physical review. E, Statistical, nonlinear, and soft matter physics

Bar-Sinai Y, Spatschek R, Brener EA, Bouchbinder E.
PMID: 24483372
Phys Rev E Stat Nonlin Soft Matter Phys. 2013 Dec;88(6):060403. doi: 10.1103/PhysRevE.88.060403. Epub 2013 Dec 10.

The strength and stability of frictional interfaces, ranging from tribological systems to earthquake faults, are intimately related to the underlying spatially extended dynamics. Here we provide a comprehensive theoretical account, both analytic and numeric, of spatiotemporal interfacial dynamics in...

Solidification in syntectic and monotectic systems.

Physical review. E, Statistical, nonlinear, and soft matter physics

Hüter C, Boussinot G, Brener EA, Spatschek R.
PMID: 23005773
Phys Rev E Stat Nonlin Soft Matter Phys. 2012 Aug;86(2):021603. doi: 10.1103/PhysRevE.86.021603. Epub 2012 Aug 28.

We present theoretical studies of syntectic and monotectic solidification scenarios. Steady-state solidification along the liquid-liquid interface in a syntectic system is considered by means of a boundary-integral technique developed previously. We study the case of small asymmetry of the...
