Stability Check
You can run a stability check for a force-deflection curve function to ensure that the defined force-deflection curve represents a valid spring.
Click Graph/Stability on the Graph Function dialog box to run a stability check on the defined function. You can also display the result of the stability check.
For a force-deflection curve to pass the stability check, the following criteria must be satisfied:
The force-deflection curve must pass through the origin (0,0).
The force must be nonpositive for negative deflections and nonnegative for positive deflections.
The force must have nonnegative slopes.
