Introduction
Multiscale computational modeling techniques in study and design of 2D materials: recent advances, challenges, and opportunities
I am pleased to share our latest open-access article, just published in #2DMaterials.
Call for nominations of Extreme Mechanics Letters Young Investigator Award 2024
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.
The award is made annually to the corresponding authors of the paper who received their Ph.D. no more than 10 years prior to the year of award. Corresponding authors who have yet to receive a Ph.D. will also be considered and self-nominations are allowed.
Cambridge University - PhD Studentship in Data-driven mechanics
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.

Stress rate for Johnson-Cook material model
I am using Johnson-Cook material model to simulate foam response, but am confused about which stress rate definition the material model uses. The manual mentions that Abaqus/Explicit uses Green-Naghdi stress rate for viscoelastic materials, but the Johnson-Cook model definition shows viscoplastic behavior, while the elasticity limi depends on the strain rate. Thus I am confuesd if Abaqus/Explicit uses Jaumann or Green-Naghdi stress rate for Johnson-Cook material model. Can someone please guide me,

Bulk and fracture process zone contribution to the rate-dependent adhesion amplification in viscoelastic broad-band materials
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.
