Needle insertion simulation by arbitrary Lagrangian-Eulerian method

Stud Health Technol Inform. 2011:163:710-2.

Abstract

In this paper, we performed needle insertion simulation considering needle tip shape by Arbitrary Lagrangian-Eulerian (ALE) method. ALE method is suitable for the large deformation and a fracture. To evaluate developed model, we compared the needle deflection between experimental results and simulation results. As a result, errors in each needle between both results were less than 3 mm.
