Dynamic Response of Multibody Systems with Multiple Clearance Joints [PDF]
Journal of Computational and Nonlinear Dynamics, 2011 A general methodology for the dynamic modeling and analysis of planar multibody systems with multiple clearance joints is presented. The inter-connecting bodies that constitute a real physical mechanical joint are modeled as colliding components, whose dynamic behavior is influenced by the geometric, physical and mechanical properties of the contacting

Bone-to-bone and implant-to-bone impingement : a novel graphical representation for hip replacement planning [PDF]
, 2020 Bone-to-bone impingement (BTBI) and implant-to-bone impingement (ITBI) risk assessment is generally performed intra-operatively by surgeons, which is entirely subjective and qualitative, and therefore, lead to sub-optimal results and recurrent ...
