Postdoctoral Position Opening at Stanford University

Prof. Wei Cai at the Mechanical Engineering Department of Stanford University is seeking a postdoctoral researcher to lead a project on the modeling of dislocations dynamics in the presence of hydrogen.  The major task of this project is to enable/perform Dislocation Dynamics simulations with hydrogen effects using the ParaDiS program. Molecular dynamics simulations may be required to provide physical input to the Dislocation Dynamics model.  The postdoctoral researcher is also expected to collaborate with external experimentalists working on this project.

Viscoelastic normal indentation of nominally flat randomly rough contacts

Viscoelastic materials are receiving increasing attention in soft robots and pressure sensitive adhesives design, but also in passive damping techniques in automotive and aerospace industry. Here, by using the correspondence principle originally developed by Lee and Radok and further extended by Ting and Greenwood, we transform the elastic solutions of Persson for contact of nominally flat but randomly rough surfaces to viscoelastic indentation. As an example, the cases of step loading and of the response to a single cycle of harmonic loading are studied.

New Program Directors in Mechanics-Focused Programs at NSF

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.

Universal Deformations in Inhomogeneous Isotropic Nonlinear Elastic Solids

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.

Comparative Biomechanics of Hagfish Skins & Planar Biaxial Testing

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.

Precipitation during creep in magnesium-aluminum alloys

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.

Variational principles for nonlinear pde systems via duality

Amit Acharya

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 for nonlinear dislocation dynamics

Amit Acharya

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.

On Hashin's Hollow Cylinder and Sphere Assemblages in Anisotropic Nonlinear Elasticity

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.
