using a local coordinate system to define shear directions
It is sometimes convenient to give shear and general traction directions with respect to a local coordinate system. The following two examples illustrate the specification of the direction of a shear traction on a cylinder using global coordinates in one case and a local cylindrical coordinate system in the other case. The axis of symmetry of the cylinder coincides with the global z-axis. A surface named SURFA has been defined on the outside of the cylinder.
In the first example the direction of the shear traction,
, is given in global coordinates. The sense of the
resulting shear tractions using global coordinates is shown in Figure 34.4.3–3(a).

system whose axis coincides with the axis of the cylinder. The sense of
the resulting shear tractions using the local cylindrical coordinate system is shown in Figure 34.4.3–3(b).

Data lines to define a general surface traction vector, a surface shear traction vector, or a general shell-edge traction vector:
First line:
1. Surface name.
2. Distributed load type label TRVEC, TRSHR, EDLD, TRVECNU, TRSHRNU, or EDLDNU.
3. Reference load magnitude, which can be modified by using the *AMPLITUDE option.
4. 1-component of the traction vector direction. 5. 2-component of the traction vector direction. 6. 3-component of the traction vector direction.
For a two-dimensional or axisymmetric analysis, only the first two components of the traction vector direction need to be specified. For the shear traction load labels TRSHR and TRSHRNU, the loading direction is computed by projecting the specified traction vector direction down upon the surface in the reference configuration. For nonuniform loads in Abaqus/Standard the magnitude and traction vector direction must be defined in user subroutine UTRACLOAD. If given, the magnitude and vector will be passed into the user subroutine in an Abaqus/Standard analysis.
