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.

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.

Cephalopod-inspired Design of Electro-mechano-chemically Responsive Elastomers for On-demand Fluorescent Patterning

Qiming Wang, Gregory R. Gossweiler, Stephen L. Craig*, Xuanhe Zhao*

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.

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 Li_xSi thin films. To do so, we vary the rate of lithiation of amorphous silicon thin films and simultaneously measure stresses.

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.
