基于有限元素法的颅脑碰撞损伤模拟方法

1 Introduction With the development and advancement of society and computer technology, finite- element method (FEM) has becomes more and more popular in solving problems in projects. In the field of biomechanics, FEM is also an important method, which is effective, accurate, low- lost and applied. We can use FEM to build up the model of complicated geometrical object, to calculate the whole and partial stress and displacement and also the regular- ities of distributions, to compare the re…

A Development of Method for The Cranium Brain Front Crash Simulation Based on Finite Element Method

This paper presents a human brain 3D finite element model, base on the human brain CT scan image, by the technologies of image processing and meshing, which consisted of left and right brain, cerebellar ,falx cerebri and cerebellum. The model has nodes and elements. With it we simulate a brain front crash process, and get the curves which describe the process' s speed, ener- gy, strain and stress. This develops a technology foundation of the whole head finite element model. Such knowledge would be helpful in the treatment of injury through identifying the mechanism of trauma and in protecting the pilot during ejection.
