Computational Model of the Eye for Primary and Secondary Blast Trauma
Abstract
This report describes the FY11 research accomplishments and their significance. In this first year of the project, we focused on developing the experimental and modeling tools for an innovative dynamic inflation test method for characterizing the stress-strain response and rupture conditions of the tissue of the eye-wall under blast conditions. Specifically, we designed and built a shock tube test system and began developing a constitutive model for the stress-strain response of the cornea and sclera that incorporates the anisotropic collagen lamellar structure. The shock-tube test system and constitutive model will be used in FY12 to measure the dynamic stress-strain response and rupture conditions of human cornea and sclera, and to develop a finite element model of the globe that features detailed of the microstructure and macrostructure of the cornea and sclera. We have made significant progress towards Specific Aim 1 of the project, which is to characterize the high-rate anisotropic stress response of the cornea and sclera, and Specific Aim 3, which is to develop a computational model of the eye in the human head.
