Stress curve axial force

The following options are available for specifying the stress/load curve:

Constant: The load determined in the system calculation (and the coressponding stress) are considered constant, corresponds to a stress ratio R = 1

Alternating: The load determined in the system calculation (and the coressponding stress) are considered as (positive) maximum value, the minimum value has the same amount but negative sign, corresponds to a stress ratio R = -1

Pulsating: The load determined in the system calculation (and the coressponding stress) are considered as (positive) maximum value, the minimum value is 0, corresponds to a stress ratio R = 0

Amplitude specification: The amplitude (A) with which the stress/load oscillates around the mean value can be specified. For positive mean stress, the stress ratio is R=(1-A)/(1+A), for negative mean stress R=(1+A)/(1-A). For the DIN 743 calculation, the load determined in the system calculation (and the corresponding stress) is taken as the mean value. For the calculation according to the FKM guideline, the load determined in the overall system (and the corresponding stress) is regarded as the upper value.
