Two PhD positions in computational mechanics at the University of Tennessee

Two PhD positions are currently available in the Computational Laboratory for the Mechanics of Interfaces at the University of Tennessee - Knoxville (http://clmi.utk.edu). Research topics are in the following areas:

 

1. Modeling of aluminum alloys using dislocation density based crystal plasticity methods.

2. Fracture in composite materials using a Discontinuous Galerkin method for debonding

 

Periodic boundary condition on non-rectangular RVE

Dear friends,
Hi. I'm working on multiscale modeling of soft tissues. For micromechanical modeling of the tissue i consider an RVE with sinusoidal edges as figure 1. 

I imposed periodic boundary conditions on the RVE using corner nodes as master nodes and define the displacement of the other nodes on the boundary related to these master nodes displacements using constraint equations as figure 2.

Post-doctoral position at Polytechnique Montréal in the simulation of the shot peening process

Dear All

I am currently looking for post-doctoral candidates to work on the simulation of the shot peening process by coupling discrete and dynamic finite element simulations. This is a two-year position. The project is in collaboration with 4 major aerospace companies and involved 6 other PhDs and 2 PDFs. 

The applicants should have a very strong background in computational mechanics.

Pseudomagnetic Fields in a Locally Strained Graphene Drumhead

Recent experiments reveal that a scanning tunneling microscopy (STM) probe tip can generate a highly localized strain field in a graphene drumhead, which in turn leads to pseudomagnetic fields in the graphene that can spatially confine graphene charge carriers in a way similar to a lithographically defined quantum dot (QD). While these experimental findings are intriguing, their further implementation in nanoelectronic devices hinges upon the knowledge of key underpinning parameters, which still remain elusive.

Variation of Stress with Charging Rate due to Strain-Rate Sensitivity of Silicon Electrodes of Lithium Ion Batteries

Silicon is a promising anode material for lithium-ion batteries due to its enormous theoretical energy density. Fracture during electrochemical cycling has limited the practical viability of silicon electrodes, but recent studies indicate that fracture can be prevented by taking advantage of lithiation-induced plasticity. In this paper, we provide experimental insight into the nature of plasticity in amorphous LixSi thin films. To do so, we vary the rate of lithiation of amorphous silicon thin films and simultaneously measure stresses.

Looking for Postdoctoral Position

Dear imechanica members,

My name is Likun and I am posting this blog in searching for postdoctoral positions in Computational Solid Mechanics.

I obtained Ph.D. in Computational Mechanics at Carnegie Mellon University. My thesis work involves developing multiscale method for retrieving slow-time scale behavior from molecular dynamics.

I also have several years' research experience in multiscale analysis and phase-field modeling of hysteresitic behaviror in active materials.  

Seek program or software for 3d crack propagation in soft tissue

Dear all,

I am looking for a program or software, which allow me to have a quick example for demostrating 3d crack propagation in soft tissue. Can someone share your suggestion on that? At the same time, some references related are also appreciated. Thanks a lot in advance. 

Best wishes,

Lei

Micromechanics of hierarchical materials: a brief overview

A short overview of micromechanical models of hierarchical materials (hybrid composites, biomaterials, fractal materials, etc.) is given. Several examples of the modeling of strength and damage in hierarchical materials are summarized, among them, 3D FE model of hybrid composites with nanoengineered matrix, fiber bundle model of UD composites with hierarchically clustered fibers and 3D multilevel model of wood considered as a gradient, cellular material with layered composite cell walls.

Hamilton's principle

I continue to receive inquiries about the monograph Hamilton's Principle in Continuum Mechanics, published in 1985 as Research Notes in Mathematics No. 139 by Pitman Publishing, Ltd. Now out of print, it is in the public domain and is attached here. My initial objective in writing it was to discuss the theoretical foundations of the applications of Hamilton's principle to mixtures that I had developed with D. S. Drumheller and others during the preceding decade.
