*SECTION POINTS
Locate points in the beam section for which stress and strain output are required.

This option is used as model data in Abaqus/Standard and Abaqus/Explicit in conjunction with the *BEAM GENERAL SECTION option and as history data in Abaqus/Standard in conjunction with the *BEAM SECTION GENERATE option.

When used in conjunction with the *BEAM GENERAL SECTION option and a predefined library section, it locates section points in the beam section for which axial stress and axial strain output are required.

When used in conjunction with the *BEAM GENERAL SECTION, SECTION=MESHED option, it locates elements and integration points in the beam cross-section model for which stress and strain output are required and provides material data and derivatives of the warping function required for determining stress and strain output.

When used in conjunction with the *BEAM SECTION GENERATE option, it associates a user-defined section point label with elements and integration points in the beam cross-section model for which stress and strain output are required during the subsequent beam analysis.

Data lines to locate section points for output when used in conjunction with the *BEAM GENERAL SECTION option and a predefined library section: 

First line:

  1. Local -position of first section point.

  2. Local -position of first section point.

  3. Local -position of second section point.

  4. Local -position of second section point.

Continue giving coordinate pairs for as many points as needed. At most four pairs of points can be specified on any data line. If the point (0,0) is specified as the last entry on a line, it will be ignored unless it is the only point requested.

Data lines to locate elements and integration point numbers for meshed sections when used in conjunction with the *BEAM GENERAL SECTION, SECTION=MESHED option: 

First line:

  1. Section point label.

  2. Two-dimensional model element number.

  3. Integration point number.

Second line:

  1. Young's modulus, E.

  2. Shear modulus in user-defined 1-direction, .

  3. Shear modulus in user-defined 2-direction, (for isotropic materials =).

  4. Material orientation angle, , measured counterclockwise from the beam local 1-direction.

  5. Local -position of the integration point with respect to the centroid.

  6. Local -position of the integration point with respect to the centroid.

  7. Derivative of the warping function with respect to the local 1-direction and the shear center.

  8. Derivative of the warping function with respect to the local 2-direction and the shear center.

Repeat this set of data lines for as many integration points as needed.

Data lines to locate elements and integration point numbers in the cross-section model when used in conjunction with the *BEAM SECTION GENERATE option: 

First line:

  1. Section point label.

  2. Element number.

  3. Integration point number.

Repeat this data line as often as necessary to specify the elements and integration points.
