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.
摘要
在本文中，我们采用任意拉格朗日-欧拉（ALE）方法进行了考虑针尖形状的针插入模拟。ALE方法适用于大变形和断裂情况。为了评估所开发的模型，我们比较了实验结果和模拟结果之间的针偏转情况。结果表明，两种结果中每根针的误差均小于3毫米。
