On laminated structures under flexure
If you design laminated structures, such as sandwich panels, you might be interested in knowing that the through-the-thickness normal stress, properly disregarded in homogeneous structures, may play a fundamental role in triggering delamination.
Abstract call for Thematic Session 'SM12 - Plasticity, viscoplasticity and creep' - ICTAM2024 (Daegu, South Korea, Aug 25-30, 2024)
Dear Colleagues,
within the 26th International Congress of Theoretical and Applied Mechanics (ICTAM2024) to be held in Daegu, South Korea, 25-30 Aug 2024, Henrik M. Jensen (Aarhus University, Denmark) and myself are organising the Thematic Session 'SM12 - Plasticity, viscoplasticity and creep'.
We would like to invite you to contribute to this Thematic Session.
The Extended Abstract Submission is open until January 15, 2024.
Best regards,
Multiscale computational mechanics Postdoc position at the University of Wyoming
The Computations for Advanced Materials and Manufacturing Laboratory (CAMML) in the College of Engineering and Physical Science at the University of Wyoming has an immediate opening for a Postdoctoral Researcher, in the area of multiscale reduced order modeling and design of heterogeneous materials under volumetric and interfacial damage. The project will build on our existing work in Refs. [1-3], and further advance it for modeling of lithium-ion battery system.
Ruobing Bai will be the next Editor of iMechanica Journal Club
Ruobing Bai of the Northeastern University will be the next Editor of the iMechanica Journal Club. The Journal Club was initiated in January 2007, soon after the launch of iMechanica. It has quickly grown into a flagship feature of iMechanica, epitomizing the vibrant topics and dynamic researchers at the frontier of mechanics.
Discussion of fracture paper #39 - Dynamic Fracture on a Molecular Level
Dynamic fracture is a never-ending story. In 1951, EH Yoffe obtained an analytical solution for a crack of constant length travelling at constant speed along a plane. She used a Galilean transformation to get a solution for arbitrary speeds. The situation seems strange with a crack tip where the material breaks and a lagging tip where the material heals. However, there are applications. One that I encountered was several mode II cracks that travel in the contact plane between a brake pad and a brake disc. The moving cracks were blamed for the causing squeaking noise when braking.

In recent years, Machine Learning (ML) has become increasingly prominent in Solid Mechanics. Its diverse applications include extracting unknown material parameters, developing surrogate models for constitutive modeling, advancing multiscale modeling, and designing architected materials. In this Journal Club, we will focus our discussion on the recent advances and challenges of ML when experimental data is involved. With broad community interest, as reflected by the increasing number of publications in this field, we have recently published a review article in Applied Mechanics Reviews titled “Recent Advances and Applications of Machine Learning in Experimental Solid Mechanics: A Review”. Moreover, a recent insightful paper from Prof. Sam Daly’s group also discussed some perspectives in this field. In this Journal Club, we would like to introduce and share insights into this exciting field.
Post-doctoral position in mesoscale plasticity
The Materials Theory Group at the School of Materials Engineering of Purdue University has a post-doctoral opening in the area of Mesoscale Plasticity of Irradiated Crystalline Solids. The postdoc will use discrete and continuum dislocation dynamics to investigate the deformation and fracture of structural alloys for fusion applications. A background in continuum mechanics and crystal plasticity is required for this position. The ideal candidate is one who is strongly interested in the fundamental aspects of deformation and fracture of metals and alloys and related computational modeling, and must have excellent programming skills in Fortran and/or C++. For inquiry about this position, please send an email to Professor Anter El-Azab (aelazab [at] purdue.edu).Any interested candidate may send a resume with list of publications, half a page statement of research interests, and the names of two or three references to the email above. The Materials Theory Group performs theoretical and computational research in the areas of mesoscale plasticity and dislocation dynamics, radiation effects in materials, microstructure evolution, thermal transport, and computational methods for materials science and mechanics.
The position is open now until filled.
