... of the art models such as the Abaqus superelastic model, without losing any of the major capabilities that are already widely adopted. These features include better representation of the superelastic loops under compression which is needed to accurately assess bending—a primary response mode in slender...

... lubricants, including silicone oil and a medical grade silicone dispersion, were also studied. In addition, the needles underwent successful perpendicular bending tests and cannula stiffness tests. Finally, fluid flow tests determined fluid flow rates through the needles. Experimental results were compared...

... for the testing of stents under various stresses and application frequency. However, these machines generally test with small bending angles or they apply nonphysiological axial, radial and torsional loads; thus they are not idealized for motions to mimic accurate biomechanical motion. Specifically...

... of the colon by inserting a flexible tube with about 3/8 in diameter into the anus, and then advancing it slowly, under visual control, into the rectum and through the colon. This procedure is often onerous due to that the driving of the bending section (tip) of the scope and perforation may occur...

... is described using the Seelecke-Muller-Achenbach single-crystal model whose parameters are experimentally derived from stress-strain characteristics of the SMA tendon measured at different temperatures. These characteristics are used to optimize the design parameters of the catheter to maximize the bending...

... required to squeeze the drug from each bottle was measured, tensile testing was performed on the bottle wall, and stiffness of the nozzle tips was studied via bend testing. The thickness of the bottle walls and the inner diameter (ID) of the nozzles were also recorded. The work required to expel the drug...

...H. M. Hsiao; S. Prabhu; A. Nikanorov; M. Razavi During normal breathing, the kidneys move up and down due to the diaphragm motion and the renal artery subsequently experiences bending. Whether bending of the renal artery during respiration impacts stent bending fatigue was not previously known...

... the cost, pain, and risk of exploratory surgery. One method to achieve this objective is to observe bending strain from spinal rods implanted during surgery. A system has been developed that will attach to the spinal instrumentation rods, transmit strain information wirelessly, and without the use...
