*PLASTIC M1
16.14 *PLASTIC M1: Define the first plastic bending moment behavior for frame elements.
This option can be used only in conjunction with the *FRAME SECTION option. It describes the bending
moment in a frame element as a function of the plastic rotation about the first cross-section direction.
Product: ABAQUS/Standard

Data lines to define the variation of yield moment M
1
0 with plastic rotation:
First line:
1. Bending yield moment about the first cross-section direction.
2. Plastic rotation about the first cross-section direction.
Repeat this data line as often as necessary to define the relationship between the bending moment and
the plastic rotation about the first cross-section axis. At least three pairs of data are required.
