The Hamilton-Jacobi equation of classical mechanics is approached as a model reduction of conservative particle mechanics where the velocity degrees-of-freedom are eliminated. This viewpoint allows an extension of the association of the Hamilton-Jacobi equation from conservative systems to general Newtonian particle systems involving non-conservative forces, including dissipative ones. A geometric optics approximation leads to a dissipative Schr¨odinger equation, with the expected limiting form when the associated classical force system involves conservative forces.

Postdoc positions are available at Jiangsu University, China. Those possessing PhDs in the area of mechanical engineering and non-destructive evaluation are sought. We are particularly interested in candidates with experience in experimental mechanics, composite materials and structures etc. Also, candidates with experience in machine learning are also welcome for inter-discipline research.

We seek an outstanding PhD candidate to develop AI-ready representations of metamaterial geometries (geometrical material structures). The project will build an atlas of common metamaterial typologies and learn compact latent representations using variational autoencoders, enabling property-driven search, generative design, and optimisation for targeted physical performance.

A direct and time-saving method is presented in a paper published in the Elsevier journal Engineering Fracture Mechanics. The paper is well-written and really read-worthy. The link to it is:
