gamma_d#

module opensg.utils.shell

opensg.utils.shell.gamma_d(e, x)#

Compute the gamma_d operator for MSG-Shell formulations.

This function computes the gamma_d operator. It represents additional strain measures needed for the Timoshenko model.

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

  • x (ufl.SpatialCoordinate) – Spatial coordinates

Returns:

ufl.Tensor – 6x4 matrix representing additional strain measures
