I am glad to present a recent set of papers highlighting the noteworthy properties of 1D periodic waveguides generated by a quasicrystalline sequence. The concept of canonical configuration explains how to obtain a periodic frequency spectrum and why this outcome is connected to trace mapping:

I see references to his "untimely death".  Yet, I have never been able to find out what happened.  I'm curious, does anyone know what happened to him?

Incidentally, many of his papers can be found at the following link for free:

I expect some of his papers would be of interest to mechanicians.

Three fully supported Ph.D. positions are open immediately in Advanced Hierarchical Materials by Design Labat the University of Alabama on multiscale modeling of materials and processes. The research directions are in the following fields:

1.     Additive Manufacturing (1 position): The goal of this project is to model the additive manufacturing process and to develop new alloys for additive manufacturing.

An immediate postdoc position is open in Advanced Hierarchical Materials by Design Lab at the University of Alabama on multiscale modeling of materials and processes.

ANSYS, Inc. has been investing time and resources into their knowledge resources and academic program and their recent contribution to the community is the "Ansys Innovation Courses". These are on-demand physics-based courses that are free for everyone which empowers students and professionals to visualize, reinforce, and rapidly master key physics concepts, with the help of simulations.

Hello all,

I am looking for the following paper: Nash, C. D. "Fatigue of self-healing structure-a generalized theory of fatigue failure." MECHANICAL ENGINEERING. Vol. 89. No. 2. 345 E 47TH ST, NEW YORK, NY 10017: ASME-AMER SOC MECHANICAL ENG, 1967.

Unfortunately, I couldn't find it anywhere. Even I ordered it through RACER but they sent the abstract to me. I would really appreciate it if someone can provide me with this paper.

regards,
Faezeh

Dear Colleagues,

We hope you and your families are all doing well during these challenging times.

This is a reminder to submit an abstract to the "Instabilities in Solids and Structures" symposium for the 2020 IMECE.
Due to COVID-19 the conference this year will be virtual (please see https://event.asme.org/IMECE for more info). Note that the final deadline is Friday, July 31.
