Defining Fatigue Events

You define six fatigue events based on the four static studies. One sitting study based on a child's weight of 50 Pounds is used. Scale factors are used for weights of 100 and 200 Pounds.

1. In the Simulation study tree, under the TopFace study, right-click Loading (-Constant Amplitude-) and click Add Event .
2. In the Add Event (Constant) PropertyManager, do the following to define the first fatigue event:
   1. Set Cycles to 7500.
   2. Set Loading Type to Loading Ratio.
   3. Set Loading Ratio to 0.25.
   4. In the Study Association box, click the cell under the Study column and select Sitting.
   5. In the Scale cell, verify that 1 appears.
      Click Keep Visible to define the remaining five fatigue events without closing the PropertyManager.
   6. Click .
   The program creates Event-1 in the Loading folder.
3. Repeat the above procedure to define the fatigue events as described in the following table.

   No. of Cycles	Loading Ratio	Study	Scale Factor
   2000	0.25	Sitting	1.83 = [(100+10)/(50+10)]
   500	0.25	Sitting	3.5 = [(200+10)/(50+10)]
   7500	0.25	Standing-50	1.0
   2000	0.25	Standing-100	1.0
   500	0.25	Standing-200	1.0

4. Click to unpin the PropertyManager.
