INITIAL CONDITIONS
5. Value of third plastic strain component, .
Give the initial plastic strain 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 plastic strain components must be given in the local system (“Orientations,”
Section 2.2.5 of the ABAQ US Analysis User ’s Manual).
Repeat this data line as often as necessary to define initial plastic strains in various elements or element
sets. Plastic strains must be defined at all section points within an element.
Data lines for TYPE=PORE PRESSURE if the USER parameter is omitted:
First line:
1. Node set or node num ber.
2. First value of fluid pore pressure,
.
3. Vertical coordinate corresponding to the above value.
4. Second value of fluid pore pressure,
.
5. Vertical coordinate corresponding to the above value.
Omit the elevation va lues and the second por e pressure value to define a constant pore pressure
distribution.
Repeat this data line as often as necessary to define the fluid pore pressure at various nodes or node
sets.
No data lines are required for TYPE=PORE PRESSURE, USER.
Data lines for TYPE=POROSITY:
First line:
1. Element number or element set label.
2. Initial porosity.
Repeat this data line as often as necessary to define initial porosity in various elements or element sets.
Data lines for TYPE=PRESSURE STRESS:
First line:
1. Node set or node num ber.
2. Equivalent pressure stress, p.
Repeat this data line as often as necessar y to define the press ure stress at various nodes or node sets.
