Duke University will host on April 24, 2020 the 31th Annual Robert J. Melosh Competition for best papers by graduate (or recently graduated) students.

The deadline for extended abstract submission is January 20, 2020. 

Students interested in participating can find more details about the format of the competition and submission requirements at

and 

The Department of Civil Engineering at Stony Brook University has started a search for 3 tenure-track faculty positions at the assistant professor or associate professor level with a desired start date of September 2020. We seek to fill the positions (one each) in the following areas:

1. Geotechnical Engineering. For this position, we are primarily interested in applicants who have expertise in energy geotechnics and coastal geotechnics. Also of interest is environmental geotechnics.

Dear Colleagues:

We cordially invite your participation in the mini-symposium

“Advances of Machine Learning in Material Design, Modeling and Processing” (MS226)

at the 14th World Congress on Computational Mechanics (WCCM XIV) to be held on July 19-24, 2020 in Paris, France. This is a great opportunity for researchers, graduate students and post docs who are working on this emergent field to share their experiences and discuss on recent progress.

Fully funded PhD positions in the area of meta-materials, computational mechanics and wave propagation available in the Department of Mechanical and Nuclear Engineering at Kansas State University. Research will be in topics related to the mechanics of metamaterials and the mechanics of amorphous or granular media.  

Students often have a tough time understanding the crack driving force in an elementary course on fracture mechanics.

A recent free access article has been published on a fluid analogy to the crack driving force and the Riabouchinsky free streamline problem for ideal fluid flow around two plates.  Hopefully this analogy can aid in the visualization.

The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of modeling of thermal transport in crystalline solids. The postdoc will use Boltzmann Transport Equation approach to investigate the phonon and electron thermal transport in crystalline solids with defects. Applicants with closely related theory background in physics, materials science, mechanical engineering, or other majors are encouraged to apply. The ideal candidate is one who is strongly interested in the fundamental concepts of thermal transport and related computational modeling, and must have excellent programming skills. To apply, please send a curriculum vita with list of publications and the names and contact information of two references to Professor Anter El-Azab (aelazab@purdue.edu). The cover letter should explain the relevance of the applicant background to the postdoc research topic above. This position is part of the DOE funded Energy Frontiers Research Center for Thermal Energy Transport under Irradiation (TETI), and the postdoc is expected to collaborate with a large team of theorists and experimentalists. The position is available now and will remain open until filled.

I attach the slides of my talks at last week’s MRS meeting in Boston on two topics:

• Fatigue-resistant stretchable materials

• Integrated soft materials

Dear Colleagues,

We would like to cordially invite you to the Computational Geomechanics mini-symposium at the ASCE EMI 2020 Conference, which will take place on May 26–29, 2020 at Columbia University in NYC. The abstract submission is now open until January 15, 2020 (Link: https://submissions.emi2020.org). The mini-symposium description is given below:

Position description: Four postdoctoral research fellows and two PhD positions are now open for ERC Starting Grant wth focus on nano energy harvester. The project is financially supported by ERC Starting Grant from Horizon2020.

Topic

Machine learning-based approaches for modeling and numerical simulation of advanced materials.

Preferred background

Recently, there has been a growing interest in investigating the multi-functional properties of novel types of metamaterials, metastructures, and metacomposites based on triply periodic minimal surfaces (TPMS). TPMS have been discovered more than 160 years ago and thanks to additive manufacturing (3D printing) they become reality only recently and opend the doors for several applications.

How to provide a structure with a force lying on a fixed line?
We provide the answer to this question in our paper: Bigoni and Misseroni (2019) Structures loaded with a force acting along a fixed straight line, or the “Reut’s column problem”.

A PhD student is sought to perform research on systems engineering theory relying on the mathematics of probability theory, decision theory, game theory and social choice theory.  The student will be supported under an NSF grant in the Mechanical Engineering department of George Mason University and work with Dr. George Hazelrigg.  If interested, please contact Dr. Hazelrigg at ghazelri@gmu.edu.

Mechanical mismatches between implanted electronics and biological tissues can lead to inaccurate readings and long-term tissue damage. Here, we show that functionalized multi-walled carbon nanotubes twisted into helical fibre bundles that mimic the hierarchical structure of muscle can monitor multiple disease biomarkers in vivo. The flexible fibre bundles are injectable, have a low bending stiffness and display ultralow stress under compression.

The HetSys team are recruiting its second cohort of enthusiastic students from across the physical sciences who enjoy using their mathematical skills and thinking flexibly to solve complex problems to join our new EPSRC Centre for Doctoral Training in Modelling of Heterogeneous Systems at the University of Warwick, UK. Our exciting range of PhD projects can be found on our webpage.

We are looking for an Academic Associate to join the Department of Engineering.  This post is part-time and in addition you will be required to register for a PhD part-time for the duration of the 5-year post. Part-time PhD fees will be paid by the Department for 5 years and the PhD will be in the area of 3D printing of Smart Shape Memory Materials for Advanced Sensors and Actuators.

PhD Title: 3D printing of Smart Shape Memory Materials for Advanced Sensors and Actuators

Measuring forming limit diagrams (FLDs) is a time consuming and expensive process. Machine learning (ML) methods are a promising route to predict FLD of aluminium alloys. In the present work, we developed a machine learning (ML) based tool to establish the relationships between alloy composition / thermomechanical processing route to the material's FLD.
