This paper reported the fracture behavior of polymer-based nanocomposites reinforced by carbon nanotubes (CNTs). In order to solve the problem associated with the dispersion and re-agglomeration of CNTs, three dimensional CNT sponge was prepared and incorporated into the epoxy through the monomer infusion process. The fracture toughness and critical energy release rate of the nanocomposites were enhanced by more than 100% and 250%, respectively.

One postdoctoral position is immediately available in the Department of Mechanical and Design Engineering at Hongik University in Sejong, Republic of Korea. 

The postdoc candidate should have a strong background in computational mechanics of granular materials (especially, in particle-level high-speed contact/impact of solids), numerical methods (such as DEM and FEM), and computational code development with C/C++, Fortran and/or Python. 

A fully funded 2 year postdoc position is available at Penn State University in the Department of Engineering Science and Mechanics. The research is in the area of elastodynamic modeling of wave propagation and scattering in polycrystals. Candidates with a strong background in mathematics, elasticity, and elastic waves are encouraged to apply. Interested candidates can send their CV to kube [at] psu.edu.

I am looking to recruit a highly motivated and independent postdoctoral researcher to study, theoretically and computationally topics related to the dynamics of metamaterials, with specific emphasis on wave phenomena.  The position is available immediately, and potentially relevant backgrounds for the position include:

1. Phononic crystals

2. Acoustic or phononic bandgaps

3. Non-reciprocal wave propagation
