The unified mechanics theory (UMT) was used to develop a model to predict the fatigue life of pre-corroded steel samples with BCC structure. Details of the experimental validation are also provided.
A position as a Post-doc in the Innovative and Smart Infrastructure Group (ISIG) at the University of Tennessee working with Dr. Wierschem is available starting in Fall 2020. This position is available to US Citizens only. This post-doc will be involved in a research project on vibration isolation. The ideal candidate will have experience in structural dynamics with a PhD in Civil, Mechanical, or Aerospace Engineering or a related field. Interested candidates should email Dr. Wierschem (nwiersch at utk.edu) with a CV.
The use of 3D printed metal structures is taking a very fast ramp-up in industry. General Electric has demonstrated the possibility of printing titanium fuel injectors for their LEAP engine, EADS has printed a nacelle hinge bracket for the Airbus A320, Boeing is printing plastic inlet ducts for high-altitude aircrafts, hip implants and other prosthetics are exploiting the design freedom of additive manufacturing (AM),..

Description: Outstanding applications are invited to join the Department of Mechanical Engineering at UCL as part of an EPSRC industrial CASE (iCASE) PhD studentship. The PhD project is being jointly supervised by Professor Ian Eames and Dr Emad Moeendarbary from the Department of Mechanical Engineering (University College London, UCL) and Dr Alireza Azarbadegan from BP plc (British multinational oil and gas company).
This is the "part II" of my PhD thesis.
It addresses the problem of finding the dynamic cyclic response of mechanical systems experiencing dry friction with a particular focus on the influence of varying normal and tangential loads. I first start from a single degree of freedom model and gradually increase the complexity of the system. In the last chapter I address a system with 12 degrees of freedom which shows localized vibration states, that are very similar to solutions known in other physics fields like optics and fluid dynamics.
Shear banding and stick-slip instabilities have been long observed in sheared granular materials. Yet, their microscopic underpinnings, interdependencies and variability under different loading conditions have not been fully explored. Here, we use a non-equilibrium thermodynamics model, the Shear Transformation Zone theory, to investigate the dynamics of strain localization and its connection to stability of sliding in sheared, dry, granular materials. We consider frictional and frictionless grains as well as presence and absence of acoustic vibrations.
Dear iMechanicians,
I would like to inform you about the workshop WCFA2016-VFA, which is this year organized with the focus set on Vibration Fatigue Analysis. The workshop will be held at the Czech Technical University in Prague, Czech Republic from November 8 to November 10, 2016. The introductory lessons in the first day will be presented by Prof Darrell Socie, Prof Milan Ruzicka and Dr Jan Papuga, while the main topic - Vibration Fatigue Analysis - will follow in next two days and will be covered by Dr Neil Bishop.
Employment as an assistant researcher (Post-doc) at the project OPUS from National Centre of Science.
