Position Title: Post-doctoral Research Associate

Location: School of Mechanical Engineering, Purdue University, West Lafayette

Contact: Prof. Thomas Siegmund, siegmund@purdue.edu

Start Date: As soon as possible, latest by Fall 2021

Project Title: Bone Hydration to Reduce Microcracking and Fracture Risk

The Mechanics of Infrastructure Materials research group are looking to hire a Postdoctoral Research Associate (PDRA) to work in the EPSRC project NEXTGEM. The project, led by Dr Emilio Martínez-Pañeda, aims at combining phase field methods and electro-chemo-mechanics modelling to resolve the scientific challenges holding back the applicability of hydrogen embrittlement models.

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

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

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.

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.

Quasi-crystalline Structural Composites:

higher order symmetries and vibration localization

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.

I am looking for motivated students to join my research group and work towards their PhD in the area of computational cardiovascular biomechanics.

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.

The associated press-release provides a compelling lay-person summary: https://www.caltech.edu/about/news/contrary-to-previous-belief-strike-sl...

We revisit Nye's lattice curvature tensor in the light of Cartan's moving frames. Nye's definition of lattice curvature is based on the assumption that the dislocated body is stress-free, and therefore, it makes sense only for zero-stress (impotent) dislocation distributions. Motivated by the works of Bilby and others, Nye's construction is extended to arbitrary dislocation distributions. We provide a material definition of the lattice curvature in the form of a triplet of vectors, that are obtained from the material covariant derivative of the lattice frame along its integral curves.

In this paper we investigate the possibility of elastodynamic transformation cloaking in bodies made of non-centrosymmetric gradient solids. The goal of transformation cloaking is to hide a hole from elastic disturbances in the sense that the mechanical response of a homogeneous and isotropic body with a hole covered by a cloak would be identical to that of the corresponding homogeneous and isotropic body outside the cloak.

I am seeking a PhD student to work on the design and modeling of morphing solids and shells. The position is fully funded and is available at the Department of Mechanical and Aerospace Engineering at the University of Missouri – Columbia.

Applicants will have a BS or an MS or an Engineering degree in a relevant area (Mechanical or Civil Engineering, Physics or Applied Mathematics). Knowledge of Python, Matlab and of an FEA software (e.g., Ansys) is a plus.

The prestegious Horace Mann medal is bestowed on selected Brown University graduate school alums who have made a significant impact in their fields. In 2021, this award goes to a mechanician whom we all know very well--Professor Ares Rosakis.
