The Computational Mechanics and Methods Group (CM3) in the Department of Mechanical Engineering at the University of Kentucky is seeking highly self-motivated individuals who have great interests in the broad research area of computational mechanics and methods. Ideal applicants should have strong background in solid mechanics and great interests in computational modeling & simulation using nonlocal meshfree/meshless methods, such as peridynamics.

We are looking for an applicant with Master degree in Mechanical Engineering or allied fields with prior experience in finite element modelling and mechanical/damping characterization.  The position is for a period of up to 36 months, depending on the performance of the candidate. There might be possibility of registering for the MS (by research) or PhD program at the Indian Institute of Technology Kharagpur, if found suitable in the corresponding selection procedure of these programs.

Advanced Master MAPMOD

Digital Materials and Advanced Processes Modelling

MAPMOD is a one-year full-time postgraduated program in line with industrial needs for high level competences in high added value components or equipment manufacturing in fields such as aeronautics, energy, automotive…

Ph.D. positions starting from 2021 Fall and 2022 Spring in YIN group at NCSU.

The research program will focus on soft robotics and mechanical metamaterials. Candidates with high self-motivation, experimental or modeling background and interests in mechanical engineering, materials science and engineering, and mechanics are highly encouraged to apply.

The outstanding and brilliantly written paper, "Modeling of Dynamic Mode I Crack Growth in Glass Fiber-reinforced Polymer Composites: Fracture Energy and Failure Mechanism" by Liu, Y, van der Meer, FP, Sluys, LJ and Ke, L, Engineering Fracture Mechanics, 243, 2021, applies a numerical model to study the dynamics of a crack propagating in a glass fiber reinforced polymer. The paper is a school example of how a paper should be written. Everything is well described and carefully arranged in logical order.

AbstractPatterned surfaces have proven to be a valuable design to enhance adhesion, increasing hysteresis and the detachment stress at pull-off. To obtain high adhesive performance, soft materials are commonly, used, which easily conform to the countersurface, such as soft polymers and elastomers. Such materials are viscoelastic; i.e., they show rate-dependent properties. Here, the detachment of two half spaces is studied, one being flat and the other having a dimple in the limit of short range adhesion and a power law rate-dependent work of adhesion, as observed by several authors.

The realistic particles in lithium batteries have unique microstructures, which should be determined in the analysis of chemo-mechanical behaviors during charge/discharge cycles. In this paper, an image-based finite element method (IBFEM) is developed to investigate the volume expansion, Li-ion distribution, and diffusion-induced stress (DIS) of a realistic particle.

If you are curious about application of machine learning techniques in mechanics problems, our latest paper is probably interesting for you. In this paper, we are proposing a micromechanics-based artificial neural networks model for short fiber composites.

Dear iMechanicians, 

The 19th National Congress of Theoretical and Applied Mechanics (USNC/TAM) will be hosted by the University of Texas at Austin, at the AT&T Executive Education and Conference Center from June 19-24 in 2022. Proposals are now invited to organize symposia at the 19th USNC/TAM. For more information, go to: http://www.usnctam2022.org/.

The Journal Club for April 2021 presents a concise review of the so-called variational phase-field fracture theory for brittle and cohesive fracture. Topics include the pioneering work of Griffith on brittle fracture in 1920, Barenblatt's cohesive zone model in 1959, to Marigo/Francfort's variational formulation of Griffith's brittle fracture 78 years later and the Bourdin's phase-field regularisation of MF's model. Also discussed is recent models for cohesive fracture, the role of the length scale parameter, solver for the coupled PDEs and some applications.

Dear Colleagues,

We mourn the death of Arthur Peter “Art” Boresi, professor emeritus of civil and architectural engineering at the University of Wyoming, Laramie, and formerly of theoretical and applied mechanics at the University of Illinois at Urbana-Champaign, who died February 15, 2021, at age 96 at Laramie.

Please find attached a tribute to Art, written by his colleagues James W. Phillips (UIUC), Richard J. Schmidt (U. of Wyoming) and Ken P. Chong (George Washington U).

Sincerely,

Yuri Bazilevs

Dear Mechanicians, dear colleagues, dear authors and readers of scientific publications,

We are very happy to inform you that the first overlay journal in mechanics, which was launched in August 2020, has just published its first paper.

I am looking for a talented and highly motivated student for a fully-funded 3-year PhD position to work on soft robotics locomotion in my group at the Center for Soft Robotics, the University of Southern Denmark.

Apply online until April 15, 2021.

Context

As part of a Europeanproject between different industrial partners and Universities, the main objective of the doctoral position will be to develop methodologies in thecontext of data-driven stochastic multi-scale simulations.

PhD opportunity

Dr. Xiaoyu Tang’s group in the Department of Mechanical and Industrial Engineering at Northeastern University has multiple fully funded Ph.D. positions in the area of Fluid Mechanics and Soft Matter. Research in the group focuses on multiphase flow, microfluidics, and active colloidal systems, using both experimental and numerical techniques. Selected candidates are expected to start in Fall 2021. Visiting students/scholars are always welcome.

Qualification

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).
