fedoo.weakform.PlateShearEquilibrium

class PlateShearEquilibrium(plate_properties, true_drilling_rotation=True, drill_stiffness_coefficient=0.01, name='', nlgeom=None, space=None)

Mechanical weak form for the transverse shear contribution in plate models.

This weak form is derived from PlateEquilibriumFI but isolates and returns only the transverse shear terms (stiffness/force contributions).

It is intended solely to be paired with a PlateKirchhoffLoveEquilibrium weak form (which carries the membrane and bending energy) to manually construct selective reduced integration (SRI) elements.

Note

Drilling Rotation (RotZ) Handling: The simple drilling penalty stiffness is excluded from this reduced integration weak form when true_drilling_rotation is False, ensuring it is instead evaluated using full integration to avoid rank deficiency.

Note

This function is dedicated to pedagogical purposes (e.g., demonstrating manual SRI assembly). For production or performance-critical applications, prefer using PlateEquilibrium, which automatically handles selective reduced integration internally.
