The Extreme Mechanics Letters (EML) Young Investigator Award (YIA) 2024 edition is organized by the journal and Elsevier to honor the best paper by a young scientist. The papers must have been published in volumes 63-69, from 2023 to 2024.

Mechanical properties of materials are usually measured by simple one-dimensional tests. The growing field of data-driven mechanics requires development of experimental methods to obtain large quantities of multi-axial data from a single test. To complement this data is the requirement to develop computational methods that can deal with the inevitable measurement noise.

The contact between a rigid Hertzian indenter and an adhesive broad-band viscoelastic substrate is considered. The material behavior is described by a modified power law model, which is characterized by only four parameters, the glassy and rubbery elastic moduli, a characteristic exponent n and a timescale tau0.

The Kang Group for Bioinspired Extreme Materials is looking for outstanding candidates to join the group. We have openings as below. Due to the large volume of applications received, we will contact only those selected for interviews. Thank you for your understanding.

In differential geometry, rigidity theory investigates whether a surface can deform by pure bending without stretching. The central problem is to find or disprove the existence of isometric deformations.

Classical examples in the "discrete" category include:

We are looking for a Postdoc Fellow in the area of structural mechanics (4D printed morphing structures). The successful candidate will work in Hopkins Extreme Materials Institute (HEMI), Johns Hopkins University on a fully funded research project.

Duties
• Design, fabricate and conduct mechanical tests and numerical simulations on morphing structures with programmable materials such as shape memory polymer or other similar materials
• Write technical reports, papers and research proposals
• Guide the graduate students in the group

It is 50 years that people use models of viscoelastic fracture which assume the fracture energy in the process zone is independent on the crack speed. This has been assumed in the cohesive models by Knauss and Schapery and then by the dissipation theory of de gennes and Persson-Brener.  Researchers like to use this model because it is simple.   Unfortunately, it does not work, as we show in adhesion experiments in the recent JMPS paper attached.   We obtain nice results for a broad band power law material, but these results only work at very low speeds.

Abstract

Dear colleagues,

Universidad Loyola Andalucía (Seville, Spain) is currently offering a postdoc position (2 years) within the “BatCAT” project, at the Department of Engineering. The aim of this project is to develop a multiscale multiphysical simulation framework of the manufacturing process of electrodes, by means of a coupled thermo-diffusive-mechanical numerical model (DEM- or FEM-based).

Dear colleagues,

We invite you to see the preprint of our new paper Lagrangian approach to origami vertex analysis: Kinematics that will appear in Philosophical Transactions of the Royal Society A. Here we show how the Lagrangian approach to origami facilitates the exploitation of symmetry, formulate reduced order compatibility conditions for some symmetric foldings, and obtain analytical expressions for the kinematics of some degree 6 and degree 8 origami vertices.
