Dear Colleagues,
I am writing to share with you my article titled, "Precipitation during creep in magnesium-aluminum alloys" , which has been published in the journal Continuum Mechanics and Thermodynamics.
Lightweight magnesium-aluminum alloys show significant tension-compression asymmetry under creep loading. This work offers an explanation of this phenomenon.

Dear Colleagues:
We would like to cordially invite you to attend the mini-symposium entitled "320: Mechanics and Physics of Active Materials" orinized at the 19th U.S. National Congress on Theoretical and Applied Mechanics. The conference will be held in Austin, Texas, June 19–24, 2022 (http://www.usnctam2022.org/congressMS).
Dear iMechanicians, I would like to share our recent work on a drop confined by two adhesive graphene sheets (as illustrated below).

A formal methodology for developing variational principles corresponding to a given nonlinear
pde system is discussed. The scheme is demonstrated in the context of the incompressible
Navier-Stokes equations, systems of first-order conservation laws, and systems of Hamilton-
Jacobi equations.

An action functional is developed for nonlinear dislocation dynamics. This serves as a fi rst step
towards the application of eff ective field theory in physics to evaluate its potential in obtaining
a macroscopic description of dislocation dynamics describing the plasticity of crystalline solids.
Connections arise between the continuum mechanics and material science of defects in solids,
eff ective field theory techniques in physics, and fracton tensor gauge theories.
The scheme that emerges from this work for generating a variational principle for a nonlinear
pde system is general, as is demonstrated by doing so for nonlinear elastostatics involving a stress
response function that is not necessarily hyperelastic.

Start date: between 1 November 2021 and 1 December 2021
Duration: 18 months (first phase of the project)
HOW TO APPLY?
The Mechanical and Aerospace Engineering (MAE) Department at Syracuse University is seeking applications for a tenure-track Assistant Professor position in the field of Solid Mechanics. This position is part of an ambitious Invest Syracuse Cluster Hire Initiative in the broad area of bioinspired science and technology.
Two Ph.D. positions are available for January 2022 at the Multiscale Material Modeling Lab at the University of North Carolina at Charlotte. The Ph.D. students will develop and use tools such as machine learning, finite elements, and molecular dynamics to study the mechanical properties of materials. If interested please email your CV to atabarra [at] uncc.edu.
