-
fenics_shells.von_karman.kinematics.e(u, theta)¶ Return the membrane strain tensor for the Von-Karman plate model.
\[e(u, theta) = \mathrm{sym}\nabla u + \frac{\theta \otimes \theta}{2}\]Parameters: - u – In-plane displacement.
- theta – Rotations.
Returns: UFL form of Von-Karman membrane strain tensor.
