TRIAXIAL TEST DATA: Provide triaxial test data.
This option is required if some or all of the m aterial parameters that define the exponent form of the
*
DRUCKER PRAGER option are to be calibrated from triaxial test data.
Product: ABAQUS/Standard
Type: Model data
Level: Model

Optional parameters:
A
Set this parameter equal to the value of the material constant a if it is known and is held fixed at the
input value. Omit the parameter and its value if a is to be obtained from the calibration.
B
Set this parameter equal to the value of the material constant b if it is known and is held fixed at the
input value. Omit the parameter and its value if b is to be obtaine d from the calibration.
PT
Set this parameter equal to th e value of the material constant
if it is known and is held fixed a t
the input value. Omit the paramete r and its value if
is to be obtained from the calibration.
Data lines to specify triaxial test data:
First line:
1. Sign and magnitude of confining stress, .
2. Sign and magnitude of the stress in loa ding direction,
.
Repeat this data line as often as necessary to give the yield stress at different levels of confining stress.
