Estudo do tempo de processamento para análises do comportamento mecânico de córneas via simulações numéricas

Abstract

Cornea and sclera are parts of the ocular globe external surface, providing protection tothe internal components and keeping the shape of eye refractive. The corneal structure is composedby epithelium, endotheliumn and stroma, being this last one the main responsible for the mechanicalproperties of the cornea. Biomechanical studies involving the Finite Element Method (FEM) canreveal important mechanical characteristics of the cornea, however these studies usually requirehigh computational cost. This work proposes a study of the processing time for mechanical behavioranalysis of human corneas by using FEM, taking into consideration computational models withlow complexity. Simulations were performed using a commercial software finite element analysis tomeasure the displacement at the central point of the cornea in which the amount of elements andnodes of the model was changed in order to compare the results.
