兔眼晶状体弹性模量测定及有限元模拟

he finite element models of rabbit lenses of different age groups were estblished on the basis of compression experiment of rabbit lens in this paper. The elastic modulus of the model were adjusted to make the simulation data coincide with the experimental data, and by this way, the elastic modulus values of the lenses in different age groups were obtained. The results show that: with the increase of age, the lens elastic modulus also increases. The stress and strain distribution of inner lens was obtained under the compressed load by the simulated stress and strain cloud. The work of this paper provides the reference for understanding the change rule of age-related lens stiffness.
