mini-symposium on SIMULATION AND MODELING OF MEDICAL DEVICES AND IMPLANTS

Gong, Xiao-Yan (Primary Organizer)
Rebelo, Nuno (Co-Organizer)

This minisymposium discusses computational methods and their applications in medical devices and implants. A broad area of topics is sought to include numerical modeling of the medical devices or implants in-vitro, the materials that these devices or implants are made of, the interactions of these devices or implants with the in-vivo environment, prediction of the device or implant fatigue life through numerical analysis, coupling of multiple areas of computational mechanics and body motion simulations. Typical contributions to this forum might come from academic institutions, manufacturers, software developers and regulatory agencies such as FDA. The use of numerical simulation in medical devices and implants has been significantly increased in recent years, primarily due to lack of accuracy, practicality, and the expense of the in-vitro testing. New technical developments that rely on modeling of devices and implants and their interactions with human body are changing the culture of the industry, allowing it to deliver better performance and more durable devices and implants. In addition, better understanding of the human body has seen a tremendous utilization of computational mechanics for large deformation, fluid-structural coupled modeling. This is particularly true for cases, such as heart valves and stents, where device integrity is critical yet the tests are neither effective nor reflective to the reality. The nature of all of these applications typically involve some of the most challenging aspects in both fluid and structural mechanics, such as nonlinear material behavior under large strains, large and nonlinear deformations, failure and fatigue fracture, contact, fretting and wearing. Continuing hardware advances have permitted an increased demand for computational results that deliver greater complexity and fidelity than ever before with improved accuracy and better representation of the biological interactions.The purpose of this mini-symposium is to provide a forum for technical presentations and exchange of ideas and to establish communication and collaboration between academic, industrial and government researchers and users in the field of computational mechanics for medical devices and implants applications. Papers dealing with theoretical developments, multidisciplinary coupling, algorithms and numerical methods, implementation and parallel computational issues, constitutive modeling, experimental validation, and practical applications are all welcome.
