I would say this a little differently: There are things (like crystal structure) that are natural to represent using a non-orthogonal...

DaveE replied to the thread I Non-orthogonal bases.There are lots of materials you might run across that naturally have non-orthogonal basis to describe anisotropic behavior like strength...

DaveE replied to the thread I Non-orthogonal bases.This appears quite often in engineering. We use eigenvalues and eigenvectors to model dynamic systems to make the analysis easier do and...
