Viscoelasticity is the property of a material that exhibits some combination of both elastic or spring-like and viscous or flow-like behavior.

The postdoc fellow will work with Associate Research Professor Feng Zhu (https://fzhu.wse.jhu.edu/) in Hopkins Extreme Materials Institute (HEMI), a division of Johns Hopkins University.

Duties

·         Conduct drop tower and ballistic impact tests on lithium-ion battery cells and system

·         Develop numerical models to simulate the battery tests and analyze the failure responses

Université Côte d'Azur and CEMEF Mines ParisTech, in the French Riviera, currently have a Ph.D. position in computational geomechanics.

The goal of the project is to study the microstructural evolutions that take place on rocks of the lithosphere by using full field numerical simulations. The idea is to directly account for the physical mechanisms responsible for the microstructural evolution of the rocks and that are thought to be at the origin of strain localization and might help us to understand the origin of tectonic plates.

I am looking to hire a postdoc for a 2 year appointment to work with me on FE simulation of wind turbine tower structures with opportunities for collaboration in uncertainty quantification, other energy structures, other thin-walled structures, and more. I have two active projects on wind turbine towers that include collaborations with one large OEM and one startup manufacturer that will be the primary emphasis of the postdoc.

In this work published in PNAS (https://www.pnas.org/content/118/19/e2100077118), we present compliant 3D frameworks that incorporate microscale strain sensors for high-sensitivity measurements of contractile forces of engineered optogenetic muscle tissue rings, supported by quantitative simulations.

Abstract: 

PhD positions in Computational Mechanics - Fracture and Contact Mechanics

We just opened at IMT School for Advanced Studies Lucca a call for PhD students for the next cycle of the PhD Programme in Systems Science, Track Computer Science and Systems Engineering.

People interested in computational mechanics and tribology should mention MUSAM -Multi-scale Analysis of Materials- in their motivation letter and in the online form.

Tensile tests are used to determine how materials behave under tension load. In a simple tensile test, a sample is typically pulled to its breaking point to determine the ultimate tensile strength of the material. The amount of force (F) applied to the sample and the elongation (∆L) of the sample are measured throughout the test.

Ares Rosakis and collaborators across three other institute have just published a fascinating account of a rather unexpected mechanism for generating  tsunamis. The paper, published in PNAS, is attached with this post.
