Introducing Wu Wei aka Irene
I began building my wooden boat in 1995, just after I moved to Beaverton, OR. I wanted a boat I could take out for [...]
ASTM Stent Radial Force Characterization
You can download a report where Dr. Paul and I explored modeling the radial force characteristics of stents andd the various details associated [...]
Phase Transformations in Nitinol
Nitinol is well suited to the design constraints imposed by medical device applications, however, only modest progress has so far been made regarding long [...]
Effects of Notches and Grain Size on Transformations in Nitinol
In this paper, we present a research methodology to characterize the effects of crystallographic orientation and grain size on the deformations and transformations in [...]
FEA and Experimental Evaluation of Superelastic Stent
The mechanical properties of Nitinol stents are normally evaluated experimentally due to complexities resulting from large deformations and material nonlinearity. Despite difficulties associated with [...]
Nonzero Mean Fatigue Testing of Nitinol
This paper describes a fatigue test protocol that was used to determine the factor of safety for a superelastic Nitinol implantable medical device. A [...]
