Hello iMechanica! My name is Ryan and I am the Founder of Mechanical Engineering HQ. I am writing here today to share an interesting development in prosthesis. Scientists have claimed that they have developed a new artificial eye that has more advanced capabilities than human eyes. Read on to see if they have achieved this feat!

Wire Arc Additive Manufacturing or WAAM techniques are attracting interest from the manufacturing industry because of their potential to produce large metal components with low cost and short production lead time. This process exists alongside other high deposition rate metal AM technologies such as powder and wire based DED. While these use either laser or an electron beam as energy source to melt a metal powder or wire, WAAM technologies melt metal wire using an electric arc.

A formal hierarchy of exact evolution equations are derived for physically relevant space-time averages of state functions of microscopic dislocation dynamics. While such hierarchies are undoubtedly of some value, a primary goal here is to expose the intractable complexity of such systems of nonlinear partial differential equations that, furthermore, remain ‘non-closed,’ and therefore subject to phenomenological assumptions to be useful. It is instead suggested that such hierarchies be terminated at the earliest stage possible and effort be expended to derive closure relations for the ‘non-closed’ terms that arise from the formal averaging by taking into account the full-stress-coupled microscopic dislocation dynamics (as done in [CPZ+ 20]), a matter on which these formal hierarchies, whether of kinetic theory type or as pursued here, are silent.
An immediate Ph.D. position is available in the Predictive Computational Engineering (PCE) Lab in the Department of Mechanical and Aerospace Engineering. The research project aims at developing novel computational methods for predictive modeling and uncertainty quantification of biomimetic-inspired materials systems. Candidate should already be in the U.S. and must have a Master's degree in engineering or applied math. A strong background in computational and applied mechanics is desired. If interested, contact Dr.
Two postdoctoral positions are available in the laboratory of physical metallurgy in CEA Saclay (France) for two years starting this Fall 2020 to work either on the thermodynamic modeling of Ti-Zr-O alloys using ab initio calculations, or on the interaction between dislocations and precipitates in Zr-Nb alloys using molecular dynamics.
1) Modeling of Ti-Zr-O thermodynamics from ab initio calculations
