No Strength
The No Strength model is intended primarily to model ponded water. When you set the Strength Type = No Strength:
- Strength Parameters are disabled since shear strength is zero (slip surfaces do not pass through a No Strength material). No Strength material contributes only its weight (and hydrostatic force) to the model.
- Water Parameters are not applicable and are disabled.
In most cases, use of the No Strength material is NOT recommended. Ponded water can be modelled in Slide2 much more easily, by simply drawing a Water Table above the External Boundary. See the Add Water Table topic for details. The No Strength material may be useful in some cases if you wish to customize the Unit Weight of Ponded Water (i.e. use a different unit weight from the Pore Fluid Unit Weight specified in Project Settings). Except for this situation, it is recommended that Ponded Water is modelled using a Water Table, rather than the No Strength material.
