Velocity Level Approximation of Pressure Field Contact Patches

Understand

Pressure Field Contact (PFC) was recently introduced as a method for detailed modeling of contact interface regions at rates much faster than elasticity-theory models, while at the same time predicting essential trends and capturing rich contact behavior.

• The PFC model was designed to work in conjunction with error-controlled integration at the acceleration level.
• Therefore a vast majority of existent multibody codes using solvers at the velocity level cannot incorporate PFC in its original form.
• In this work we introduce a discrete in time approximation of PFC making it suitable for use with existent velocity-level time steppers and enabling execution at real-time rates.
