JOINTED MATERIAL

Data lines deﬁning failure surface and ﬂow parameters (SHEAR RETENTION omitted):

First line:

1. Angle of friction, , for this system . Give the value in degrees.

2. Dilation angle,

, for this system. Give the value in degrees.

3. Cohesion, d, f or this system. (Units of FL

−2

4. Temperature.

5. First ﬁeld variable.

6. Second ﬁeld variable.

7. Etc., up to four ﬁeld variables.

Subsequent lines (only needed if the DEPENDENCIES parameter has a value greater than four):

1. Fifth ﬁeld variable.

2. Etc., up to eight ﬁeld variables per line.

Repeat this set of data lines as often as necessar y to deﬁne the dependence of the failure and surface

ﬂow parameters on temperature and other predeﬁned ﬁeld variables.

Data lines deﬁning the shear retention in open joints (SHEAR RETENTION included):

First line:

1. Fraction of elastic shear modulus retained when joints are open, . This value cannot be less

than zero.

2. Temperature.

3. First ﬁeld variable.

4. Second ﬁeld variable.

5. Etc., up to six ﬁeld variables.

Subsequent lines (only needed if the D EPENDENCIES parameter has a value greater than six):

1. Seventh ﬁeld variable.

2. Etc., up to eight ﬁeld variables per line.

Repeat this set of data lines as often as necessary to deﬁne the dependence of the shear retention on

temperature and other predeﬁned ﬁeld variables.
