Novelty/impact/significance

The Solids, Waves, Intelligence, and Mechanics (SWIM) Lab, directed by Dr. Chanseok Jeong, at Central Michigan University seeks applications for a fully-funded Master-level graduate student position in inverse modeling and wave propagation analysis.  For more information, please see the attached pdf file.   

A research assistant (RA graduate student) position and a postdoc position are immediately available at penn State in the area of computational mechanobiology. These positions will be jointly advised by Profs. Daniel Cosgrove (biochemistry) and Sulin Zhang (mechanics), and will closely collaobrate with experimetnal groups in the CSLF (DoE EFRI center) at Penn State. Interested students with solid background in computational mechanics are welcome to apply.

5.1 Elastic stress transfer, in Chapter 5. Composite mechanics: Short fibers, in Load Bearing Fiber Composites, by Michael R. Piggott, 2002

This time reading notes on a section of a well-known mechanics book are presented, due to its extreme clarity and reader-friendliness in explaining the stress transfer in fiber-reinforced composites. Personal understanding for the micromechanical model and derivations are included accordingly without specific indications.

Materials become insensitive to flaws at nanoscale: Lessons from nature, Gao, Ji, Jger, Arzt, Fratzl, PNAS, 2003

Novelty/impact/significance:

It is firstly/ingeniously demonstrated that the biological nanocomposites’ generic structure is mechanically advantageous: the nanometer size of mineral reinforcements is selected to ensure optimum strength and maximum tolerance of flaws. The derivations are simple and effective.
