*M1
13.24 *M1: Define the first bending moment behavior of beams.
This option is used to define the first bending moment behavior of beams. It can be used only in conjunction
with the *BEAM GENERAL SECTION, SECTION=NONLINEAR GENERAL option.
Products: ABAQUS/Standard ABAQUS/Explicit

*BEAM GENERAL SECTION
Optional parameters (if neither ELASTIC nor LINEAR is included, elastic-plastic response is
assumed):
DEPENDENCIES
Set this parameter equal to the number of field variable dependencies included in the moment-
curvature relationship, in addition to temperature. If this parameter is omitted, it is assumed that
the moment–curvature relationship is constant or depends only on temperature. See “Specifying
field variable dependence” in “Material data definition,” Section 16.1.2 of the ABAQUS Analysis
User’s Manual, for more information.
ELASTIC
Include this parameter if the bending moment–curvature relationship is nonlinear but elastic.
LINEAR
Include this parameter if the bending moment varies linearly with curvature.
Data lines if the LINEAR parameter is included:
First line:
1. Bending stiffness of the section about the first beam section local axis.
2. Temperature.
3. First field variable.
4. Second field variable.
5. Etc., up to six field variables.
