A Diffuse Interface Method for Earthquake Rupture Dynamics Based on a Phase‐Field Model
Journal of Geophysical Research - Solid Earth, 2023 In traditional modeling approaches, earthquakes are often depicted as displacement discontinuities across zero‐thickness surfaces embedded within a linear elastodynamic continuum.

The impact of faulting complexity and type on earthquake rupture dynamics
Communications Earth & Environment, 2022 The statistical properties of seismicity are known to be affected by several factors such as the rheological parameters of rocks. We analysed the earthquake double-couple as a function of the faulting type. Here we show that it impacts the moment tensors

Journal of Geophysical Research - Solid Earth, 2021 Megathrust earthquakes are strongly influenced by the elastic properties of rocks surrounding the fault. In contrast to friction, these properties can be derived in situ from geophysical measurements along the seismogenic zone.

Uncertainty quantification of dynamic earthquake rupture simulations [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2021 We present a tutorial demonstration using a surrogate-model based uncertainty quantification (UQ) approach to study dynamic earthquake rupture on a rough fault surface. The UQ approach performs model calibration where we choose simulation points, fit and validate an approximate surrogate model or emulator, and then examine the ...

Image-Based Numerical Investigation in an Impending Abdominal Aneurysm Rupture
Fluids, 2022 Blood flow dynamics plays a crucial role in the growth and rupture of abdominal aortic aneurysms. The aim of this study was to analyze the possibility of predicting aneurysmal rupture by numerical investigations based on diagnostic images. The blood flow

Rupture of a biomembrane under dynamic surface tension [PDF]
Physical Review E, 2012 How long a fluid membrane vesicle stressed with a steady ramp of micropipette last before rupture? Or conversely, how high the surface tension should be to rupture a membrane? To answer these challenging questions we have developed a theoretical framework that allows description and reproduction of Dynamic Tension Spectroscopy (DTS) observations.
