Abstract

The mechanical character of acoustic conduction for tympanic membrane(TM) was concerned since ear disease often resulted in conductive deafness. As TM belongs to physiologic anisotropic material, different material value should be given to corresponding element in finite element method (FEM), therefore, computing error are aroused due to the mutation of material character in the interface of different element. In this paper, TM is analyzed based on the meshless method(MM), and the results of the MM are compared with that of FEM and experiments as well. The results show that meshless method (MM) is feasible in simulating physiologic anisotropic material, and it is also more effective when calculating the amplitude of TM.
