Force, relative-displacement, and work networks in granular materials subjected to quasistatic deformation [PDF]
, 2007 To describe the heterogeneous nature of stress transmission in granular materials, the concept of the “strong” network consisting of contacts with large normal forces has been proposed by Radjaï et al. [Phys. Rev. Lett. 80, 61 (1998)].

Experimental Study on Coal Specimens Subjected to Uniaxial Cyclic Loading and Unloading
Applied Sciences, 2022 The paper represents a test investigation of the mechanical properties and acoustic emission (AE) characteristics of low-strength coal specimens subjected to cyclic loading and unloading. From the lab tests, the following conclusions can be obtained: (1)

Contact Changes near Jamming [PDF]
, 2014 We probe the onset and effect of contact changes in soft harmonic particle packings which are sheared quasistatically. We find that the first contact changes are the creation or breaking of contacts on a single particle.

Implications from ASKAP Fast Radio Burst Statistics [PDF]
, 2019 Although there has recently been tremendous progress in studies of fast radio bursts (FRBs), the nature of their progenitors remains a mystery. We study the fluence and dispersion measure (DM) distributions of the ASKAP sample to better understand their ...

Stress-strain behavior and geometrical properties of packings of elongated particles [PDF]
, 2010 We present a numerical analysis of the effect of particle elongation on the quasistatic behavior of sheared granular media by means of the Contact Dynamics method. The particle shapes are rounded-cap rectangles characterized by their elongation.
