formula reference error in GND calculation #1346

Open cheneyjin opened 2 years ago

Hi,

I found the formula reference in GND energy calculations is difference from that in the book 'Introduction to Dislocations' by Hull & Bacon. From the website https://mtex-toolbox.github.io/GND.html, reads:

wrong_dis

However, in the book by Hull and Bacon:

Energy_dislocation

So, the second formula should be :

$$ U{edge}=\frac {U{screw}}{1-\nu} $$
