Acceleration Factor

Description: Returns the value of the acceleration factor. Only available for stress-dependent models. Time required only for a Cumulative Damage model with time-varying stresses.

Field Format: [ACCELERATIONFACTOR(Source Number)(Time;Accel Stress 1;Accel Stress 2;Accel Stress 3;Accel Stress 4;Accel Stress 5;Accel Stress 6;Accel Stress 7;Accel Stress 8)]

Source Number is the associated data source number.
Time is the time at which the acceleration factor is calculated. This is required only when the source data sheet uses the Cumulative Damage model with time-varying stresses.
Accel Stress values are the acceleration stress levels for each stress type. The number of stress inputs is determined by the number of stress types in the specified data source.

Remarks:

The Source Number must be either 1, 2, 3 or 4.

The Time value must be greater than or equal to 0.
The Accel Stress values must be greater than 0.

Example:

[ACCELERATIONFACTOR(1)(0;315;;;;;;;)]

Returns:

0.4129

Note that this value will vary depending on the source data set.
