| 摘 要： | 基于人体CT图像，建立了股骨和颅骨的三维模型。采用无单元伽辽金法分析了人体股骨和颅骨生物力学冲击问题。在给定工况下，得到了股骨的应力峰值，考察了峰值出现的位置，讨论了颅骨在不同冲击速度作用下的响应。无单元伽辽金法与有限元法计算结果在峰值大小及其随速度变化趋势上均吻合较好。计算结果表明：无单元伽辽金法处理骨骼等复杂的生物...

| Abstract: | The 3D models of human femur and skull based on CT images are established. The Element-Free Galerkin （EFG） method is applied in biomechanies impacting of these two models. The max effective stress of the fumer is obtained. The places they generetad are investigated. The response of the skull under different velocities is discussed. Both the max stress value and the tendency following the velocity change are consistent with the results of the FEM. The results show that the EFG method has much convenient in dealing with Biomechanics modes, with stable results. |
