Dynamic Systems and Intelligent Machines (DSIM) Lab at the San Diego State University has an open PhD position in the areas of perception, planning, and control of autonomous systems. Highly motivated applicants with prior experience in robotics, control, and machine learning and strong programming skills and mathematical background are encouraged to apply. Applicants should have B.Sc. and M.Sc. degrees in Computer Science, Mechanical Engineering, or a closely related field.
Dear iMechanicians. I hope that you find the below work interesting - we have developed the first phase field formulation for hydrogen assisted fatigue. Fatigue crack nucleation and growth is predicted for arbitrary geometries, loading histories, and H contents. Virtual S–N curves are also obtained. You can check it here: https://doi.org/10.1016/j.ijfatigue.2021.106521
I have a request to make to physicists: Would they be willing to provide some informal feedback on my new approach to QM?
Update (2021.09.21 15:57 IST): There were unusually many blog hits for the document. ... I do like the work getting noticed, but still, I guess, a clarification is in order:
A special issue on "Mechanics of 3D-Printed Polymers and Polymer Composites", is recently launched in the journal "Polymers". If your research is related to the topic, I would like to invite you to submit your latest research developments to the special issue. For more details and submitting your manuscript, please see:

A general class of implicit bodies was proposed to describe elastic response of solids, which contains the Cauchy–Green tensor as a function of Cauchy stress. Here, we consider the buckling of solids described by such a subclass of implicit constitutive relation. We present a general linear incremental theory and carry out bifurcation analysis of a uniaxially compressed rectangular layer described by an implicit constitution. We then provide general governing equations regarding the mixed unknowns, i.e., displacement and stress fields, within the framework of finite strain deformation.

Viscoelastic materials are receiving increasing attention in soft robots and pressure sensitive adhesives design, but also in passive damping techniques in automotive and aerospace industry. Here, by using the correspondence principle originally developed by Lee and Radok and further extended by Ting and Greenwood, we transform the elastic solutions of Persson for contact of nominally flat but randomly rough surfaces to viscoelastic indentation. As an example, the cases of step loading and of the response to a single cycle of harmonic loading are studied.
