principal_stresses

compas_fea2.utilities.principal_stresses(data, ptype, scale, rotate)[source]

Performs principal stress calculations.

Parameters:

  • data (dic) – Element data from structure.results for the Step.

  • ptype (str) – ‘max’ ‘min’ for maximum or minimum principal stresses.

  • scale (float) – Scale on the length of the vectors.

  • rotate (int) – Rotate lines by 90 deg, 0 or 1.

Returns:

  • array – Vectors for section point 1.

  • array – Vectors for section point 5.

  • array – Principal stresses for section point 1.

  • array – Principal stresses for section point 5.

  • float – Maxium stress magnitude.
