For flexible electronics applications it is important to understand the behavior of electrical resistance of metal films on polymer substrates under applied tensile strain. Although the growth of resistance during tensile loading was investigated in a number of research papers, the recovery of resistance during unloading remains virtually unexplored. In this paper, substantial recovery (decrease) of electrical resistance during and after unloading is demonstrated for copper films on polyethylene terephthalate (PET) substrates subjected to a tensile strain with different peak values.

Abstract

All -

Are there good references related to acoustic heating?  I am interested in the ability to scale down the effects of this process and looking for ideas in model development to assist.

A previous post, Getting Ready for Extreme Mechanics Letters, contained the following paragraph:

“We seek papers from researchers in all disciplines. Mechanics appeals to talents of all kinds. Good mechanics has long been created by people from many fields, by Galileo, Newton, Maxwell and Faraday, as well as by Watt, Darwin, Wright brothers and Whitesides. People make discoveries in mechanics often when doing something else (e.g., in seeking evidence for the existence of God, in building cathedrals, in flying airplanes, in laying transatlantic telegraph cables, in fabricating microprocessors, in watching cells move, in fracking for gas, in inventing optical tweezers, in creating soft lithography, in developing wearable or implantable electronics). Mechanics discovered in one field invariably finds applications in other fields.”

Here I would like to give several examples of papers published in recent decade or so. I will link each paper to its citations on Google Scholar, so that you can have an overview of the influence of the paper on other researchers.
