Rotations with constant Curl are constant

We address a problem that extends a fundamental classical result of
continuum mechanics from the time of its inception, as well as answers a fundamental
question in the recent, modern nonlinear elastic theory of dislocations.
Interestingly, the implication of our result in the latter case is qualitatively di fferent
from its well-established analog in the linear elastic theory of dislocations.

Elasticity notes of Eli Sternberg

Submitted by Ruobing Bai on

Here are the elasticity notes of Eli Sternberg over many years as he taught AM 135 at Caltech. I had access to them when I was working with Prof. Kaushik Bhattacharya at Caltech during postdoc. Prof. Bhattacharya suggested making the notes publicly available via iMechanica, and below is a short note from him.
