1、Formulations include the following：
1）Pure Penalty (Default -
Program Controlled)：
2）Augmented
Lagrange：
3）Normal Lagrange：
This formulation adds an
extra degree of freedom (contact pressure) to satisfy contact
compatibility. Consequently, instead of resolving contact force as
contact stiffness and penetration, contact force (contact pressure)
is solved for explicitly as an extra DOF.
4）MPC：
For the specific case of
Bonded and No Separation Types of contact between two faces, a
Multi-Point constraint (MPC) formulation is available. MPC
internally adds constraint equations to “tie” the displacements
between contacting surfaces.
5）Beam：Beam Formulation
is available for the Bonded Type only. This formulation works by
"stitching" the contact topologies together using massless linear
Beam Elements.
2、Pure Penalty and Augmented Lagrange Contact
Formulation
3、Normal Lagrange Contact Formulation
This formulation adds an
extra degree of freedom (contact pressure) to satisfy contact
compatibility. Consequently, instead of resolving contact force as
contact stiffness and penetration, contact force (contact pressure)
is solved for explicitly as an extra DOF.
Does not require a normal contact
stiffness (zero elastic slip)
4、Multi-Point constraint (MPC) Contact Formulation
For the specific case of
Bonded and No Separation Types of
contact between two faces, a Multi-Point constraint (MPC)
formulation is available.Large-deformation
effects are supported with MPC-based Bonded contact.

Chapter 12: Soil-Pile-Structure
Analysis
You can
analyze the interaction of an offshore structure supported on one
or more piles, with an elastic or inelastic
soil. The analysis can take into account the lateral force
displacement, and the end-bearing and skin-friction responses of
the soil layers occurring at the pile location. It is not necessary
for all piles in the analysis to be situated in identical
geological strata.
Customized macros are used to model the
soil-pile interaction, with the soil data defined
in additional text files. Piles are modeled
using PIPE288 and
the surrounding soil environment is modeled using COMBIN39 elements.
The macros, along with accompanying
documentation, can be found in the Offshore extension in the ACT
Extension library in the downloads area on the Customer
Portal: https://support.ansys.com/AnsysCustomerPortal/en_us/Downloads/Extension+Library.
