Automatic Surface Mesh Intersection Algorithm of Spine and Implant FEM Models

摘要

We propose the automatic surface mesh intersection algorithm of spine and implant models. The spine-implant intersection has unique constraint: the implant model should not change as much as possible because spine-implant structure analysis simulates the process to insert a strong durable implant into a relatively weak durable spine. Through the actual simulation, we show there is no abnormal results due to automatically generated intersection regions.
