*INITIAL CONDITIONS
Data lines for TYPE=HARDENING, REBAR:
First line:
1. Element number or element set label.
2. Rebar name. If this field is left blank, the initial conditions will be applied to all rebars in the
model.
3. Initial equivalent plastic strain, .
4. Initial backstress, . (Only relevant for the kinematic hardening models.)
Repeat this data line as often as necessary to define the hardening parameters for rebars in various
elements or element sets.
No data lines are required for TYPE=HARDENING, USER.
Data lines for TYPE=HARDENING, SECTION POINTS:
First line:
1. Element number or element set label.
2. Section point number.
3. Initial equivalent plastic strain, .
4. First value of the initial backstress, . (Only relevant for the kinematic hardening models.)
5. Second value of the initial backstress, . (Only relevant for the kinematic hardening models.)
6. Third value of the initial backstress, . (Only relevant for the kinematic hardening models.)
Give the backstress components as defined for this element type in Part VI, “Elements,” of the
ABAQUS Analysis User’s Manual. In any element for which an *ORIENTATION option applies,
the backstress components must be given in the local system (“Orientations,” Section 2.2.5 of the
ABAQUS Analysis User’s Manual).
Repeat this data line as often as necessary to define the hardening parameters in various elements or
element sets. The hardening parameters must be defined at all section points within an element.
Data lines for TYPE=INITIAL GAP:
First line:
1. Element number or element set label.
Repeat this data line as often as necessary to identify various elements or element sets.
Data lines for TYPE=MASS FLOW RATE:
First line:
1. Node set or node number.
