Angle of rotation at a point in a deformed triangle
I have a 2D triangle which deforms with each vertex moving by some small ($\sin(x) \approx \tan(x) \approx x$) displacement vector. The displacement of any point in the triangle is linearly interpolat …

Angle of rotation at a point in a deformed triangle
A much simpler formula is
$$
\theta = {1 \over 2} \nabla \times u
$$
Where $u$ is displacement. The derivatives of $u$ are obtained multiplying elements of the strain-displacement matrix (p8 here) by …
