The Biological Systems and Materials Division has been focusing on embracing and serving the duality of its membership, which consists of many established members of the society and the field of theoretical and applied mechanics who are developing research programs focusing on biological systems and materials, and simultaneously numerous researchers from the biological sciences who [...] You can view an animation in real time of a crack growing in a Nitinol fatigue specimen observed using moire interferometry while the test was being conducted in our Bose Electroforce test machine that shows a moving transformation zone and perceptible fringes captured at 30 frames per second. You can download our presentation where we give results from recent in-vitro tests and advanced finite element analysis simulations as an example of a comprehensive and self-consistent engineering methodology for understanding therapeutic applications of RF tissue ablation. .
Radial force behavior is one of many engineering design criteria important to the design of implantable medical devices such as stents. Interpretation and extrapolation of bench-top data to predict in-vivo performance necessitates a thorough understanding of influence parameters such as boundary conditions and material uncertainty. An integrated modeling and test validation approach is needed to [...] Phase shifted moire interferometry of crack and transformation zone in Nitinol fatigue specimen. You can download our presentation of Nitinol fatigue and fracture initiation using phase shifted moire interferometry. |
