We are seeking a post-doctoral fellow to examine the biomechanics of arterial corrugations. Arteries are known to have a strongly-corrugated lumen. This is readily evident from histology images of the internal elastic lamina (IEL), which usually appears as a heavily-wrinkled layer. The overall goal of this research is to elucidate the biomechanics of such arterial corrugations.
Wrinkles in layered neo-Hookean structures were recently formulated as a Hamiltonian system by taking the thickness direction as a pseudo-time variable. This enabled an efficient and accurate numerical method to solve the eigenvalue problem for onset wrinkles. Here, we show that wrinkles in graded elastic layers can also be described as a time-varying Hamiltonian system. The connection between wrinkles and the Hamiltonian system is established through an energy method.
This is a quick advert to let you know about a post-doctoral research assistant (PDRA) with me. It is a 2-year research position with possible extension depending on funding and performance (see below for details).More positions will be available in future years.
A link between the local surface stress at the atomic scale to the overall behavior of the continuum system indicates a twist deformation at the free end of silicon nano-cantilever. The importance of size and crystal orientation is demonstrated (for more details of the project see:https://www.researchgate.net/publication/327768951_Surface_Stress_Effec…).
A PhD position is available at Cranfield University (UK) to study the role of overloads on fatigue failure. The candidate will develop mesocale-sensitive crystal plasticity models validated at multiple scales. The position offers a dynamic research environment and the opportunity to work closely with researchers developing computational models and performing experiments.
I now include this paper in my course on fracture mechanics.
Dear Colleague,
Dr. Saeed Zare Chavoshi and I have co-authored three review articles, concerning nanoindentation and nanoscratching at finite temperatures from the computational and experimental perspectives:
