wave propagation

Authors: Abhishek Arora, Caglar Oskay

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

Colleagues,

The Solid Mechanics--Damage and Failure team at Los Alamos National Laboratory is seeking a highly motivated and productive postdoc candidate in the area of shock compaction, with a focus on simulating the microstructure evolution of granular materials using explicit representation of microstructures.

Dear all,

The Mechanics of Complex Systems Lab at University of Illinois Urbana Champaign (https://publish.illinois.edu/mcslabuiuc/)is hiring two postdoctoral researchers in the broad area of computational mechanics and its applications to environmental mechanics.

The Finite Difference (FD) and the Spectral Boundary Integral (SBI) methods have been used extensively to model spontaneously propagating shear cracks in a variety of engineering and geophysical applications. In this paper, we propose a new modeling approach, in which these two methods are combined through consistent exchange of boundary tractions and displacements. Benefiting from the flexibility of FD and the efficiency of spectral boundary integral methods, the proposed hybrid scheme will solve a wide range of problems in a computationally efficient way.
