Sharing a new article "Finite element implementation of Field Crack Mechanics for brittle and ductile fracture" by my Ph.D. student BVSS Bharadwaja at IIT Bombay, which has been accepted for publication in Theoretical and Applied Fracture Mechanics. Also see attached. Thanks to Prof. Amit Acharya for the motivation and discussion.

It is my pleasure to share a new article titled "An Experimentally Informed Continuum Grain Boundary Model" by Syed Ansari (my Ph.D. student at IIT Bombay). This work was performed in collaboration with Prof. Amit Acharya.

A new funded PhD opportunity is available at the University of Bath. The project is on elastic tailoring of composite winglets on aircraft. 

The opportunity comes with an enhanced stipend (for students who quailfy). 

PhD start date: September 2024. Application deadline is the 30th of May 2024.

MARSS, the annual International Conference on Manipulation, Automation and Robotics at Small Scales, is a non-profit conference run by the microrobotic community and technically supported by IEEE-RAS and IEEE-NTC. MARSS2024 will be held in-person on July 01-05, 2024, in Delft, Netherlands. The conference is the flagship forum to discuss cross-disciplinary activities on 1) manipulation, automation, measurement, and characterization at micro/nano scales, and 2) all kinds of small-scale robots (nm – cm) and their applications.

A fully-funded Ph.D. position is available in the Control, Automation, and Mechatronics (CAM) lab at Kent State University, Kent, OH, starting in Spring 2025. The program is housed within the College of Aeronautics and Engineering and focuses on Mechatronics Engineering. Ideal candidates will need to have completed their master’s degree by the end of 2024 and must possess a strong foundation in controls, system identification, and machine learning, along with proficient programming skills in Python and MATLAB.

Description

The Department of Mechanical Engineering at the Technical University of Darmstadt seeks candidates at the earliest possible date for a Full University Professorship (W3) for Numerical Methods in Fluid Mechanics. We are looking for a scientist with an international reputation and visibility who will represent the field of numerical methods in fluid mechanics in research and teaching.

Dear colleagues, 

We invite you to read our article, which informs one about the extent to which resonances can be tuned in metamaterials. More precisely, our work provides tight bounds correlating the Quality-factor with peak absorption in dielectric metamaterials. The article is published in Applied Physics Letters and can be found here: https://doi.org/10.1063/5.0155092

Abstract

Funded PhD positions are available in the department of Structural Engineering at the University of California, San Diego (UCSD) in Prof. Semnani’s research group, with start date of Fall 2024 and Winter 2025. The positions are in the areas of computational mechanics, machine learning, geomechanics, landslides, material characterization and modeling, and composite materials. We are looking for highly motivated and talented individuals with bachelor’s or master’s degree in Civil and Environmental Engineering or Mechanical and Aerospace Engineering.

Around 20 years ago, I gave a fracture mechanics lecture and talked about crack initiation that happens in the plane with the largest tensile stress. True, at least if the material has isotropic properties. The students already knew where an isotropic material would give the largest stress at bending and torsion. I planned to make a desktop experiment with an icicle and a carrot. This was during the autumn with an abundance of icicles everywhere. The carrot, I found at home.

We are looking for enthusiastic students with a MSc or BSc degree to conduct research in the area of materials characterization and advanced nuclear fuels. Students with a degree in any of the following disciplines are encouraged to apply:

Applications are invited for a 2-year postdoc position in the area of finite element modeling of advanced nuclear fuels. This position is a full-time position at the University of Western Ontario, Canada, and the selected applicant can start effective immediately.

Applications are invited for a 2-year postdoc position in the area of molecular dynamic simulation of irradiation effects. This position is a full-time position at the University of Western Ontario, Canada, and the selected applicant can start effective immediately. In addition, this position is extendable for two more years, depending on the availability of funds and the applicant’s performance.

Following the previous Blog entry on 3D fracture and out-of-plane crack structures: the essential role of material disorder, we add here a related manuscript (see also attached PDF):

Size selection of crack front defects: Multiple fracture-plane interactions and intrinsic lengthscales

Many engineering disciplines, especially fluid and solid mechanics, require a solid understanding of complex analysis. We are thrilled to share that "Theory of Functions of a Complex Variable" by Richard Courant has been thoroughly revived, and upgraded, and is now freely accessible on AdaptiveBooks.org.

A position exists, for a Research Assistant/Associate in the Department of Engineering, to work on Batteries. The post holder will be located in Central Cambridge Cambridgeshire, UK.

EML Webinar (Young Researchers Forum) on 18 April 2024 will be given by Tongqing Lu at Xi'an Jiaotong University

Title: High throughput rupture experiments of soft materials

Discussion leader: Zhigang Suo, Harvard University

Postdoc positions are immediately available in the School of Traffic and Transportation Engineering (First Class Academic Discipline) at Central South University in Dr. Li's research group. Lists of topics of interest are:

1. Impact Fatigue;

2. Fluid and structure interaction;

In classical experiments, it has been found that a rigid cylinder can roll both on and under an inclined rubber plane with a friction force that depends on a power law of velocity, independent of the sign of the normal force. Further, contact area increases significantly with velocity with a related power law.

One PhD position and one Postdoctoral position are available immediately at CEMEF Mines Paris, in the French Riviera.

• PhD topic : Numerical modeling of machining processes (finishing) of parts obtained by additive manufacturing;
  Funding : French National Research Agency (ANR)
  Partners : Labomap (Ensam Cluny) & LEM3 (Université Lorraine)
