Particle stress in suspensions of soft objects

What is it about?

The dynamics of particle suspensions is of great interest and generally difficult to understand. One ingredient helping to describe suspension dynamics is the distribution of mechanical stress throughout the suspension. Those stresses are usually fluctuating in time; and these fluctuations contain valuable information. It is therefore important to access the stress fluctuations as accurately as possible. The present article describes such an approach for soft particle suspensions.

Why is it important?

This article describes an alternative way to compute local stresses in suspensions of soft particles (such as capsules, vesicles or red blood cells). Previously proposed methods provide access only to either a globally averaged stress or stresses averaged over entire particles. Accessing local stresses helps to understand stress relaxation processes and suspensions dynamics.
