Output is in a fixed cylindrical system (1=radial, 2=axial, 3=circumferential) unless a local coordinate system is assigned to the element through either the section definition (“Orientations,” Section 2.2.5) or an element property assignment (“Assigning element properties on an element-by-element basis,” Section 21.1.5), in which case output is in the local coordinate system (which rotates with the motion in large-displacement analysis). See “State storage,” Section 1.5.4 of the ABAQUS Theory Manual, for details.

Stress, strain, and other tensor components

Stress and other tensors (including strain tensors) are available for elements with displacement degrees of freedom. All tensors have the same components. For example, the stress components are as follows:

S11 | Local 11 direct stress. |

S22 | Local 22 direct stress. |

S33 | Local 33 direct stress. |

S12 | Local 12 shear stress. |

S13 | Local 13 shear stress. |

S23 | Local 23 shear stress. |
