STORM-BOTS is a new european training network (ITN) dedicated to liquid crystalline elastomers and soft robotics.

Dr John Biggins (supervisor) and Prof Mark Warner FRS (co-supervisor) are searching for a talented theorist with interests in mechanics and geometry to work on the design of soft liquid crystal elastomer (LCE) machines. The studentship is part of a new Marie Sklodowska-Curie training network called storm-bots, which will encompass 13 students across Europe working on the design and creation soft LCE machines. The soft, anisotropic materials of the project, liquid crystal elastomers (LCEs) and glasses, contract along their director on heating/illumination.

Morphology instability of substrate-supported carbon atomic layers can be harnessed to modulate physical properties and functions, which has drawn interesting attention. Curvature would be a critical factor affecting surface morphology and its stability characteristics. Infilled carbon nanotubes, that is to say carbon monolayers with curved geometry and infilled substrates, namely nanosleeves, widely exist in the literature and have many potential applications.

Thanks to Mechanics of Materials,  here is a different way to look at viscoelasticity and Hooke's law.

dear colleagues     I have written some general comments about viscoelastic models which may you find useful, mixing results from Wang Thouless Barber vs Schapery vs de Gennes Persson, etc. I conclude that Gent-Schultz is the most practical and solid approach, despite it seems empirical and too simple.  It corresponds very closely to work with Schapery model, and the finite size effects in Persson's theory are quite suspicious if not completely wrong (besides, there are two Persson's theory, one in contradiction to the other), as demonstrated by theory and actual Finite Element simulations

Applications are invited for the post of Research Associate (RA) in a project sponsored by the National Supercomputing Mission (NSM) entitled “3D elastodynamic fracture simulations” supervised by Prof. Ranjith Kunnath. NSM is a joint initiative of the Department of Science and Technology (DST) and Ministry of Electronics and Information Technology (MeITY). 

Eligibility:

The Multiscale Materials Modelling Team in WMG (University of Warwick), led by Dr Figiel, is currently seeking a Research Fellow to carry out research in the area of Computational Micromechanics of Solid-state Batteries.

One postdoc position is available in Wang Research lab (https://www.wangresearchlab.com) in the Department of Materials Science and Engineering (MSE) and the Institute of Materials Science (IMS) at the University of Connecticut (UConn).

We are now seeking to fill an academic position at Lecturer/Senior Lecturer/Reader rank for a successful academic to join the Division of Systems, Power and Energy Engineering. We specifically seek a candidate who can potentially contribute to the James Watt School of Engineering in the area of modelling of materials and/or processes at lower length scales where continuum assumption ceases to be valid.

Wang, Lu, Barber, & Thouless (WLBT, 2016) have written recently an interesting paper on the crack growth in visco-elastic and creeping materials, using a simple Maxwell "liquid" material, and the Double Cantilever Beam (DCB) model under pure moment. Using correspondence principle, they obtained an analytical solution for a viscoelastic beam on an elastic foundation, corresponding to a simple linear force-separation law for the cohesive law.

A new PhD position is availale at Tribology and Suface Mechanics (TSM) group for Fall 2021/Spring 2022. Candidates with strong mechanical engineering background on both experimental and analytical works are encouraged to apply. In particular, experience on metalic alloys, coatings, addtivie manufacturing, surface engineering and mechanics, contact fatigue, corrsoion and finite element anaylses is a plus.

We are looking for a doctoral student to work on numerical modeling of ridging of sea ice. Ridging is central to understanding the behavior of sea ice from scales varying from tens of meters up to hundreds of kilometers and has a close connection to sea ice dynamics models, which have an important role in predicting the effects of climate change. The applicant should be advanced in solid and computational mechanics and have at least average programming skills.

Two surfaces are ”sticky” if breaking their mutual contact requires a finite tensile force. At low fractal dimensions D, there is consensus stickiness does not depend on the upper truncation frequency of roughness spectrum (or ”magnification”). As debate is still open for the case at high D, we exploit BAM theory of Ciavarella and Persson-Tosatti theory, to derive criteria for all fractal dimensions. For high D, we show that stickiness is more influenced by short wavelength roughness with respect to the low D case.

We are seeking two outstanding postdoctoral candidates to complement the expertise in computational mechanics at the Department of Engineering Mechanics at KTH Royal Institute of Technology, Stcokholm, Sweden.

The research — We use x-ray phase contrast imaging (XPCI) to study deformation and fracture of materials under dynamic loading on microsecond and sub-microsecond time scales. For example, we might like to measure the change in pore size distribution of a granular material such as sandstone under impact loading.

There is an immediate opening for a post-doctoral scholar in the Hopkins Extreme Materials Institute (http://hemi.jhu.edu) at Johns Hopkins University, working with Prof. K.T. Ramesh (ramesh@jhu.edu) and Prof. Todd Hufnagel (hufnagel@jhu.edu).

Dear Colleagues,

Please find our new paper titled "Photochemical-induced phase transitions in photoactive semicrystalline polymers" published in Physical Review E. We used phase field model to investigate photochemical phase transitions in semicrystalline polymers.

Applicants must hold a PhD in Petroleum Engineering, Civil Engineering, Mechanical Engineering, Applied Mathematics, or a related discipline.

We have a number of open permanent positions at Assistant Professor level in the Department of Engineering at Durham University in the UK. We are seeking to fill posts in civil or structural engineering, and in offshore geotechnical engineering, with no restriction on nature of interests, e.g. computational or otherwise.

Dear All,

We cordially invite you to submit a manuscript for consideration and possible publication in the special issue on "Advanced numerical modelling in geotechnical engineering" in Engineering Analysis with Boundary Elements (IF=2.884).

This special issue aims to address following topics:

1. Data-driven simulation with field monitoring or experiments.

I am looking to recruit a highly motivated and independent postdoctoral researcher to study, via the development of new topology optimization techniques, various scientific issues surrounding phononic topological insulators.  An example of recent related work from my group can be found here.  The position is available for a 20-month duration, with possible extension to 36 months depending on the availability of funding, with a proposed start date of Jun

PhD position

A summer internship position is available in Joint academic-industrial project between Nordisch LLC and Michigan State University. We seeks to improve the understanding of the constitutive behavior of soft materials in extreme conditions. In particular, this is important for evaluating the long-term performance of soft materials that are used as critical components in various systems.
