Simulation of Blast Loading on an Ultrastructurally-based Computational Model of the Ocular Lens
Abstract
The report summarizes the research accomplishments during the second year of the project. Research focused on experimental tasks in support of the development of a multiscale finite element model to be used to simulate blast loading of ocular lenses. Smooth indent creep tests were conducted on porcine and human lens capsules. Potentially better images were obtained of type IV collagen meshwork ultrastructure via cryo-electron tomography. Confocal laser scanning microscopy was used to identify structure of the lens fiber cells. High strain rate compression (stress relaxation), impulse, and puncture tests were conducted on whole porcine lenses in Dr. Tusit Weerasooriya's laboratory at the Army Research Laboratory (ARL), Aberdeen Proving Ground (APG).
