| Abstract: | Finite element analysis(FEA)plays an important role in the biomechanical field.In this paper,we used FEA method in the area of ophthalmology.We generated an eyeball-extraoculars model and converted it to meet the need of FEA process.We exerted outside forces on the structure for nonlinear computation and got the distributions of displacement,stress and strain.We also discussed the relationship among(eye's) structure,outside force and move.The results corresponded with the basic theory of ophthalmology.We put forward some related aspects for discussion and advanced research as well. |
