Elastic Soil

An elastic soil material has infinite strength and can easily be defined using a constant stiffness. For elastic soil, the user must define the following parameters:

• Unit Skin Friction Stiffness - The change in unit skin friction per unit of soil displacement at each depth.
• Unit End Bearing Stiffness - The change in unit end bearing resistance per unit of soil displacement at the pile toe.

The unit skin friction stiffness is multiplied by the surface area of the pile segment to obtain the skin friction per unit of soil displacement. The unit end bearing stiffness is multiplied by the plugged cross-sectional area at the pile toe to obtain the end bearing resistance per unit of soil displacement.
