If the Poisson's ratio of the material if positive, then tensile/compressive strains in the x-direction produce compressive/tensile strains in the y- and z-directions, as shown below. Negative Poisson ...

The above equation is referred as Poisson s equation. If we have knowledge of a potential field, with the aid of Poisson s equation we can find the density of charge causing the field. The above ...

How to change between polar and Cartesian coordinates will be presented, especially for the solution of Laplacian and Poisson equations. Elementary distributional calculus and the notion of weak ...

This story appears in the December 2011 issue of National Geographic magazine. At the time of Jack the Ripper, a hard time for London, there lived in that city a mild-mannered stenographer named ...

A lengthy chapter on Sobolev spaces provides the framework that allows a rigorous treatment of existence and uniqueness of solutions for both linear time-independent problems (Poisson's equation) and ...

In this new newsletter series, The Climate Fix, we’ll be highlighting solutions that have the potential to make a difference at scale. (The series will appear on Thursdays in our biweekly ...
