Dear Mechanics Community Members:

We have great news to share! Two additional program directors have joined the Mechanics and Engineering Materials (MEM) cluster. Recall that the MEM cluster is composed of two programs devoted to the discipline of mechanics: Biomechanics and Mechanobiology (BMMB) and Mechanics of Materials and Structures (MoMS). The new hires will work across and bridge both programs, forming a complement of five program directors in total serving the needs of the ever-expanding mechanics community.

Dear colleagues,

Universal (controllable) deformations of an elastic solid are those deformations that can be maintained for all possible strain-energy density functions and suitable boundary tractions. Universal deformations have played a central role in nonlinear elasticity and anelasticity. However, their classification has been mostly established for homogeneous isotropic solids following the seminal works of Ericksen. In this paper, we extend Ericksen's analysis of universal deformations to inhomogeneous compressible and incompressible isotropic solids.

We are looking for a creative, enthusiastic, self-motivated, and qualified postdoctoral researcher to work on modeling and simulations for metallic additive manufacturing.

I am delighted to inform the mechanics community that the 2020-2021 recipient of the highly prestigious is our distinguished colleague James R. Rice, as follows

The 2020-2021 Harvey Prize Award is granted to Professor James R. Rice for fundamental and long-standing contributions to the fields of mechanics of materials and geophysics. For the J-integral, and for leadership that enhanced the understanding of friction and earthquakes.

A fully funded PhD position is available as early as Spring, 2022 in Dr. Ning Zhang’s research group at the University of Alabama (Tuscaloosa), the department of Aerospace Engineering and Mechanics. This position is in the general area of mechanics, structural and multifunctional materials with focus on mechanical and thermal properties.

The research topics include:

(1)  Polymer composites;

One Ph.D. position is available in mechanics of materials/data science area in Multiscale Materials Modeling Lab at University of Arkansas. The starting date is Spring 2022.

Students who have master’s or bachelor’s degree in physics, mechanical or materials engineering with computational or experimental background are encouraged to apply. 

In the recently published paper by the Department of Biology at College of Charleston and at Valdosta State University, researchers measured the material properties of hagfish skin and compared histological data from the skins of four hagfish species. Skin samples were subjected to uniaxial and biaxial tensile testing to study their strength, stiffness, and extensibility. ADMET eXpert 8600 Planar Biaxial testing system was used to conduct planar biaxial tests.

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 first step
towards the application of effective 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,
effective field theory techniques in physics, and fracton tensor gauge theories.

We generalize Hashin's nonlinear isotropic hollow cylinder and sphere assemblages to nonlinear anisotropic solids. More specifically, we find the effective hydrostatic constitutive equation of nonlinear transversely isotropic hollow sphere assemblages with radial material preferred directions. We also derive the effective constitutive equations of finite and infinitely-long hollow cylinder assemblages made of incompressible orthotropic solids with axial, radial, and circumferential material preferred directions.

It is my pleasure to solicit nominations for the "Eshelby Mechanics Award for Young Faculty". This award, launched in 2012, is given annually to rapidly emerging junior faculty who exemplify the creative use and development of mechanics. The intent of the award is to promote the field of mechanics, especially among young researchers. While interdisciplinary work that bridges mechanics with physics, chemistry, biology and other disciplines is encouraged, the ideal awardee will demonstrate clear inspiration from mechanics in his/her research.
