*WEAR SURFACE PROPERTIES

Specify wear properties to activate wear distance accumulation at contact surface nodes.

This option is used to specify wear properties to activate wear distance accumulation at contact surface nodes. It must appear immediately after the SURFACE PROPERTY option.

Optional parameters

DEPENDENCIES

Set this parameter equal to the number of field variable dependencies included in the definition of the wear coefficient in addition to wear distance, contact pressure, and temperature. If this parameter is omitted, it is assumed that the wear coefficients have no dependencies or depend only on wear distance, contact pressure, and temperature. See Material Data Definition

FRIC COEF DEPENDENT

Set this parameter equal to YES if the Archard’s wear equation depends explicitly on the friction coefficient.

Set this parameter equal to NO (default) if the Archard’s wear equation does not depend on the friction coefficient.

REFERENCE STRESS

This parameter is required if UNITLESS WEAR COEF=YES.

Set this parameter equal to the magnitude of hardness of the material forming the wear surface.

UNITLESS WEAR COEF

Set this parameter equal to YES if the wear coefficient is dimensionless.

Set this parameter equal to NO (default) if the wear coefficient has dimensions of inverse of stress.

Data lines to define the wear coefficient

First line

  1. Wear coefficient, φ w e a r (or alternatives φ ˜ w e a r , φ ^ w e a r , or, φ ¯ w e a r depending on the specific form of the Archard's wear equation).

  2. Surface wear distance, W. If this value is omitted, the wear coefficient is assumed to be independent of the wear distance.

  3. Contact pressure, p . If this value is omitted, the wear coefficient is assumed to be independent of the contact pressure.

  4. Surface temperature, T . If this value is omitted, the wear coefficient is assumed to be independent of the surface temperature.

  5. Surface field variable, f 1 .

  6. Surface field variable, f 2 .

  7. Etc., up to four field variables

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

  1. Surface field variable, f 5 .

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

Repeat this set of data lines as often as necessary to define the wear coefficient as a function of the surface wear distance, contact pressure, surface temperature, and predefined surface field variables.
