PhD Position on Shear Dilatancy in Concentrated Emulsions-
**_PhD position on shear dilatancy in concentrated emulsions_**

Job description

In this PhD project, you will combine theoretical and numerical modeling to fill a persistent gap in our understanding of the mechanics of soft solids.

When you twist a solid cylinder, its height spontaneously changes. This is one example of shear dilatancy, a well known but poorly understood nonlinear effect in solid mechanics. Shear dilatancy occurs in numerous types of soft matter, including gels, grains, pastes, and foams. Despite this ubiquity, we cannot reliably predict the amplitude or even the sign of the effect - most materials expand, but some contract. The fundamental and unresolved challenge is to identify a necessary and sufficient set of physical mechanisms responsible for shear dilatancy in soft solids.

Recent experiments revealed that concentrated emulsions possess a rare property - they can be tuned to display positive or negative shear dilatancy. These systems are therefore uniquely suited to test hypotheses on the origins of shear dilatancy. In this project, you will use pen-and-paper modeling in continuum mechanics, together with molecular dynamics simulations of attractive emulsions, to perform these tests.

**Requirements**:
We seek a student with a passion for fundamental research who is driven primarily by scientific curiosity.

Conditions of employment

The TU Delft offers a customisable compensation package, discounts on health insurance, and a monthly work costs contribution. Flexible work schedules can be arranged.

For international applicants, TU Delft has the Coming to Delft Service. This service provides information for new international employees to help you prepare the relocation and to settle in the Netherlands. The Coming to Delft Service offers a Dual Career Programme for partners and they organise events to expand your (social) network.
