gamma_e

module opensg.utils.shell

opensg.utils.shell.gamma_e(e, x)

Compute the gamma_e operator for MSG-Shell formulations.

This function computes the gamma_e operator. It represents the strain measures in terms of the spatial coordinates.

Parameters:

• e (tuple) – Local frame vectors (e1, e2, e3)

• x (ufl.SpatialCoordinate) – Spatial coordinates

Returns:

ufl.Tensor – 6x4 matrix representing the strain measures
