sig_out_per_node
- opsvis.sig_out_per_node(how_many='all')[source]
Return a 2d numpy array of stress components per OpenSees node.
Three first stress components (sxx, syy, sxy) are calculated and extracted from OpenSees, while the rest svm (Huber-Mieses-Hencky), two principal stresses (s1, s2) and directional angle are calculated as postprocessed quantities.
- Parameters
how_many (str) – supported options are: ‘all’ - all components, ‘sxx’, ‘syy’, ‘sxy’, ‘svm’ (or ‘vmis’), ‘s1’, ‘s2’, ‘angle’.
- Returns
- a 2d array of stress components per node with
the following components: sxx, syy, sxy, svm, s1, s2, angle. Size (n_nodes x 7).
- Return type
sig_out (ndarray)
Examples
sig_out = opsv.sig_out_per_node()
Notes
s1, s2: principal stresses angle: angle of the principal stress s1
