TL;DR: In this paper, the impact of thermal pressurization and mineral decomposition reactions under seismic deformation conditions (e.g., slip rates of about 1 m/s) triggered by shear heating, to the stability of a saturated fault material was studied.

TL;DR: In this paper, a 2D example of a circular arc crack is presented and a simple approximation for compliances of non-flat cracks is provided. But the authors do not consider the effect of nonflat geometries on the overall elastic properties of the material.

TL;DR: Two fractional calculus approaches in the framework of continuum mechanics are revisited and compared in this article, where analogies and differences between the two models are outlined, and a non-local approach is proposed, according to which long-range interactions between material particles are opportunely modelled in the equilibrium equations.
Abstract: Two fractional calculus approaches in the framework of continuum mechanics are revisited and compared. The former is a local approach, which has been proposed to investigate the behaviour of fractal media. The latter is a non-local approach, according to which long-range interactions between material particles are opportunely modelled in the equilibrium equations. Analogies and differences between the two models are outlined.

TL;DR: In this article, the sliding friction anisotropy at the nano-, micro-, and macroscales with respect to surface asperity orientation was investigated and the mechanisms behind this phenomenon were explored.
Abstract: The work reported in this paper aims at understanding sliding friction anisotropy at the nano-, micro-, and macroscales with respect to surface asperity orientation and exploring the mechanisms behind this phenomenon. Experiments were conducted by probing surfaces with grooves parallel or perpendicular to the direction of relative motion. Continuum mechanics analyses with the FEM and a semi-analytical static friction model and the atomic molecular dynamics simulation were performed for the mechanism exploration. Friction anisotropy was understood from the differences in contact area, surface stiffness, stiction length, and energy barrier from the continuum mechanics prospective and from that in the stick–slip phenomena at the atomic level.
