Dear iMechanica Community,
I'd like to ask for advice on modelling reflection and transmission coefficients when two bars with different cross-sectional areas contact each other and are exposed to pulse loading.
I have modelled this process in Abaqus/Explicit as a two-dimensional simulation. The investigation was conveniently done as a parametric study, defining the lateral dimension as parameter. Both bars are slim (length 2 m, diameter 2 cm) and elastic.
I have openings for two post-doc positions in my new research group at the Institute of Mechanical Engineering at the Ecole Polytechnique Fédérale de Lausanne (EPFL) in Lausanne, Switzerland, where I will be moving later this year. The target start date is January 1st, 2018.
This paper aims to maximize optical force or torque on arbitrary micro- and nanoscale objects using numerically optimized structured illumination. By developing a numerical framework for computer-automated design of 3d vector-field illumination, we demonstrate a 20-fold enhancement in optical torque per intensity over circularly polarized plane wave on a model plasmonic particle. The nonconvex optimization is efficiently performed by combining a compact cylindrical Bessel basis representation with a fast boundary element method and a standard derivative-free, local optimization algorithm.

The roles of impact and inertia in the failure of a shoelace knot
The paper discusses a mechanism for the the accidental untying of a shoelace knot that many of us, including me, experience on a daily basis. The failure is sudden and catastropic as can be seen in the following video:
