Element-based loading
Distributed loads
Gravity loads as described in “Distributed loads,” Section 34.4.3, are the only distributed loads that are available for particle elements. You define gravity loading in a specified direction, and the magnitude is input as acceleration.
Element output
Output is in global directions unless a local coordinate system is assigned to the element through the section definition (“Orientations,” Section 2.2.5), 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 Guide, for details.
Stress, strain, and other tensor components
Stress, strain, and other tensors are available. All tensors have the same components. For example, the stress components are as follows:
S11 |
|
, direct stress.S22 |
|
, direct stress.S33 |
|
, direct stress.S12 |
|
, shear stress.S13 |
|
, shear stress.S23 |
|
, shear stress.Note: the order shown above is not the same as that used in user subroutine VUMAT.
