                      Prof. Jan Zeman, Czech Technical University, Prague

On June 11, 2021, in the framework of the PRIN2015 METAMATERIALS WEBINARS series, prof. Federico Bosia from Politecnico di Torino has held the webinar 

ELASTIC METAMATERIALS FOR MULTISCALE APPLICATIONS, FROM SEISMIC SHIELDS TO NON-DESTRUCTIVE TESTING. The registration of the webinar is available here. 

Dear iMechanicians,

We have contributed to the Special Issue organised by the Royal Society on occasion of the centenary of Griffith's seminal paper with a paper revisiting phase field fracture methods and their connection with conventional fracture mechanics theory. I hope that you find it of interest. (https://royalsocietypublishing.org/doi/10.1098/rsta.2021.0021)

It was reported both in experiments and computations using some classical plate theories that wrinkles can appear in a uniaxially stretched rectangular hyperelastic film with clamped-clamped boundaries and can be suppressed upon further tension. Here, based on a recently-available consistent finite-strain plate theory, we investigate this complex instability problem with isola-center bifurcation (the nontrivial solution curve begins and ends at two distinct points on the trivial line) in more depth and present an efficient numerical algorithm.

Esteemed Colleagues,

PhD positions with full financial support in the form of research assistant/teaching assistant are immediately available in the Department of Material Science and Department of Industrial and Manufacturing at Penn State University, starting Fall 2021 or Spring 2022. 

Position 1: Additive Manufacturing of Smart and Composite Materials (Polymer or Ceramic based Materials) 

Position 2: All-Solid-State Batteries

The Mechanics & Computation lab in the Mechanical Engineering Dept at IISc Bangalore has multiple openings for project assistants:

Post #1: Design & analysis of 3D printed lattices

Essential requirements:

• Expertise in Abaqus (standard + explicit)
• Good grasp of basic strength of materials
• Hands-on experience with 3D printing of plastics

Post #2: Experimental mechanics

One or two positions are available for a student to undertake a fully funded Ph.D. in Engineering at Louisiana Tech University understanding the detailed structure of the complicated heterogeneous materials in lithium ion batteries. Expected start date is Sept. or Nov. of 2021.

Requirements:

• B.S. in Engineering (Chemistry or Physics backgrounds are also suitable).

• Competitive GRE
• An interest in multi-disciplinary research in materials

One PhD position with full financial support in the form of research assistant/teaching assistant is immediately available in the Department of Mechanical Engineering at Binghamton University (SUNY), starting Fall 2021 or Spring 2022. This specific position is focused on the development of multiscale modeling of nanoplastic-biomembrane interactions combining continuum elasticity theory and particle-based simulation methods. The student will work in a diverse and inclusive research team and collaborate with experimentalists at Rochester Institute of Technology.

A postdoctoral fellow research position is availabe immediately in the Advanced Digital & Additive Manufacturing (ADAM) center at Khalifa University in Abu Dhabi in United Arab Emirates. Applicants should demonstrate research capabilities in computational modeling and experimentation in the area of additive manufacturing (3D printing).

A modified phase-field model for fracture is presented which includes the material strength and cleavage planes to quantitatively predict the crack propagation path and the mechanical response in polycrystalline brittle materials. Computational Materials Science 197 (2021) 110642 (11 pages).

Postdoc Open Positions

Postdoc positions with financial support (up to 3 years) are immediately available in the Department of Mechanical Engineering, University of Connecticut (UConn).

Dear colleagues,

I'm writing to bring to your notice the sad news that Prof. Jerry Ericksen of the University of Minnesota passed away on June 11th 2021.

Kaushik Dayal

There is an immediate opening of a postdoctoral researcher in the Mechanics of Soft Materials Lab (https://www.msm.seas.ucla.edu/) in the Department of Mechanical and Aerospace Engineering at the University of California, Los Angeles (UCLA). The research will be on experimental mechanics of soft materials, and fabrication of soft machines. The successful candidate should have a PhD degree with expertise in experimental polymer materials.

EML Webinar (Season 2) on 16 June 2021 will be given by Ju Li, MIT. Elastic Strain Engineering for Unprecedented Properties. Discussion Leaders: Sulin Zhang, The Pennsylvania State University

Time: 10 am Boston, 3 pm London, 10 pm Beijing on 16 June 2021

PhD position(s) is available for Spring 2022 in the Engineering Mechanics program in Aerospace Engineering Department at Iowa State University to perform theoretical and computational part of work on NSF-funded projects on the interaction between phase transformations and plasticity. Phase-field, micromechanical, and macroscale simulations using FEM are of interest, in close collaboration with high-pressure experiments performed in our lab. Please send vita to Prof. Valery Levitas ( vlevitas@iastate.edu )

Mode-coupling instabilities are known to trigger self-excited vibrations in sliding contacts. Here, the conditions for mode-coupling (or "flutter") instability in the contact between a spherical oscillator and a moving viscoelastic substrate are studied. The work extends the classical 2-Degrees-Of-Freedom conveyor belt model and accounts for viscoelastic dissipation in the substrate, adhesive friction at the interface and non-linear normal contact stiffness as derived from numerical simulations based on a boundary element method capable of accounting for linear viscoelastic effects.
