Rupture dynamics in model polymer systems.

Soft Matter, 2016
In this paper we explore the rupture dynamics of a model polymer system to capture the microscopic mechanism during relative motion of surfaces at the single polymer level. Our model is similar to the model for friction introduced by Filippov, Klafter, and Urbakh [Filippov et al., Phys. Rev.

On the scale dependence in the dynamics of rupture

, 2021
<p>Potential energy stored during the inter-seismic period by tectonic loading around faults can be released through earthquakes as radiated energy, heat and rupture energy. The latter is of first importance, since it controls both the nucleation and the propagation of the seismic rupture.

Nucleation Mechanism and Rupture Dynamics of Laboratory Earthquakes at Different Loading Rates

Applied Sciences (Switzerland), 2023
The loading rate of tectonic stress is not constant during long-term geotectonic activity and significantly affects the earthquake nucleation and fault rupture process. However, the mechanism underlying the loading rate effect is still unclear.

Dynamics of three-dimensional thin film rupture

Physica D: Nonlinear Phenomena, 2000
We consider the problem of thin film rupture driven by van der Waals forces. A fourth-order nonlinear PDE governs the low Reynolds number lubrication model for a viscous liquid on a solid substrate.

The 2023 Pazarcık (Kahramanmaraş, Türkiye) Earthquake (Mw: 7.7): Implications for surface rupture dynamics along the East Anatolian Fault Zone

Journal of the Geological Society, 2023
Southern Türkiye faced widespread catastrophic destruction by two devastating earthquakes on the same day. As the earthquakes occurred at 04:17 (Mw=7.7, Pazarcık, Kahramanmaraş) and 12:30 (Mw=7.6, Elbistan, Kahramanmaraş) on February 6, 2023 ...

Simulated Rupture Dynamics and Radiated Energy on Heterogeneously Damaged Faults

Journal of Geophysical Research: Solid Earth, 2023
Rupture dynamics along a heterogeneous fault is studied in the framework of the recently developed damage‐breakage rheological model. The model utilizes a fault structure accommodating shear and wear in a heterogeneous weak fault‐core a few centimeters ...

Rupture Dynamics of the 2012 Nicoya Mw 7.6 Earthquake: Evidence for Low Strength on the Megathrust

Geophysical Research Letters, 2020
Frictional properties on subduction interfaces are essential for understanding earthquake nucleation, rupture propagation, and tsunami generation during megathrust earthquakes.

GPU implementation of curved-grid finite-difference modelling for non-planar rupture dynamics

, 2020
A deep understanding of earthquake physics requires a large amount of numerical simulations on seismic wave propagation and dynamic rupture. However, the corresponding intensive computational expense of simulations at traditional CPU (central processing ...

Rupture Dynamics of Macromolecules

2013
In a series of studies we consider the breakage of a polymer chain of segments, coupled by anharmonic bonds under applied tensional force or subject to rise in temperature. The chain dynamics at the onset of fracture is studied by means of Molecular Dynamics simulation and also using analytic considerations.A deeper insight into the changes in polymer ...

The simulation of rupture dynamics from potential earthquakes around XiLuoDu reservoir dam, China

, 2020
The XiLuoDu reservoir dam located on the Jinsha River is one of the largest dams in the world. Nearby faults are very active, and two M > 7 strong earthquakes have occurred around the dam.
