Class for storing a stress result.

Provides variables to store the results from a cross-section stress analysis. Also provides a method to calculate combined stresses.

Variables:

  • sig_zz_m11 (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Normal stress (\(\sigma_{zz,M11}\)) resulting from a bending moment about the 11-axis

  • sig_zz_m22 (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Normal stress (\(\sigma_{zz,M22}\)) resulting from a bending moment about the 22-axis

  • sig_zx_mzz (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zx,Mzz}\)) resulting from a torsio moment about the zz-axis

  • sig_zy_mzz (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zy,Mzz}\)) resulting from a torsio moment about the zz-axis

  • sig_zx_vx (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zx,Vx}\)) resulting from a shear force in the x-direction

  • sig_zy_vx (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zy,Vx}\)) resulting from a shear force in the x-direction

  • sig_zx_vy (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zx,Vy}\)) resulting from a shear force in the y-direction

  • sig_zy_vy (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Shear stress (\(\sigma_{zy,Vy}\)) resulting from a shear force in the y-direction

  • sig_zz_m (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Normal stress (\(\sigma_{zz,\Sigma M}\)) resulting from all bending moments

  • sig_zxy_mzz (numpy.ndarray[Any, numpy.dtype[numpy.float64]]) – Resultant shear stress (\(\sigma_{zxy,Mzz}\)) resulting from a torsion moment in the zz-direction
