University of Cassino Selects MSC Software's Dytran to Understand Eye Injury Mechanisms Due to Blunt Impact

SANTA ANA, CA -- (Marketwire) -- May 01, 2012 -- MSC Software Corporation, the leader in multidiscipline simulation solutions that accelerate product innovation, today announced that the University of Cassino, Italian academic center has selected MSC Software's Dytran explicit nonlinear and fluid-structure interaction simulation solution to understand the processes of dynamic deformation that occurs in the human eye when subjected to blunt impact.

The detachment or tearing of the retina in the human eye as a result of a collision is a phenomenon that occurs often. To better understand this phenomenon, the University of Cassino developed a Finite Element (FE) model starting from 3D measurements of real human eyes. The model, validated through a comparison of the simulation results against measured data available in literature, was then used to study the intensity of the dynamic stress waves produced during the impact with a steel projectile, in order to assess the primary source of retina failures.

"The results of the Dytran simulations indicate that the laceration of the retina mainly occurs due to the tension resulting from the reflection of compression waves in the moments immediately following the impact, and not necessarily due to the deformation of the whole eye," said Nicola Bonora, Professor of Mechanical Design at the University of Cassino. "The availability of a reliable and validated model for the simulation enabled us to understand in detail the pathogenesis of the blunt impact phenomenon, which is particularly difficult to reproduce in a controlled and instrumented manner through physical tests in the laboratory."

"Dytran was selected from the different explicit solvers available on the market mainly because of its advanced fluid-structure interaction capabilities," added Nicola Bonora. "Practical applications of this study are found especially in the military industry, for example in the design of advanced safety and protection systems for personnel and for helicopter pilots in the event of a crash landing."

"It is deeply gratifying when simulation can play an important role in understanding phenomena of the human body and aid in research that can improve our quality of life," said Dominic Gallello, President & CEO at MSC Software.
