# Jamming in hard sphere suspensions under shear

## TL;DR

This paper investigates how shear affects the structure and jamming transition of monodisperse hard sphere suspensions, revealing that shear-induced distortions influence the transition to a jammed state similar to random close packing.

## Contribution

It introduces a theoretical framework to analyze shear-induced structural distortions and their impact on jamming in hard sphere suspensions.

## Key findings

- Shear distorts the structure factor of hard spheres at low shear rates.
- Distortions influence the transition to a jammed state.
- Jamming under shear resembles the random close packing transition.

## Abstract

We consider a system of monodisperse hard spheres immersed in a sheared fluid. We obtain the distortion of the structure factor of the hard spheres at low shear rates, within a Percus-Yevick like framework. The consequent distortion of the pair distribution function is shown to affect the transition of the hard sphere fluid into a jammed state, which is similar to the transition to the state of random close packing in the absence of shear.
