Waviness Angle

If you are performing a Probabilistic analysis with SWedge, the Joint Waviness Angle can be defined as a random variable, as follows:

  1. Select Input Data and select the Joint1 or Joint2 tab in the Probabilistic Input Data dialog.
  2. Choose a statistical distribution for the Joint1 or Joint2 Waviness Angle, and enter the appropriate statistical parameters.

TIP: An exponential distribution is often used to model the distribution of waviness angle.

Although the Waviness Angle parameter is grouped with the Joint Orientation data in the Probabilistic Input Data dialog, the waviness angle only affects the shear strength of the joint planes. It does NOT affect the wedge geometry. For the purpose of calculating the wedge geometry, the joint planes are always assumed to be perfectly flat. For details about the waviness angle implementation in SWedge see the Waviness Angle topic.
