7、of Medical Metallic Materials and Devices thatwas sponsored by ASTM Committees E08 on Fatigue and Fracture and F04 on MedicalDevices held in Dallas,TX,November,2005.It was the intent of this conference to bringtogether technical experts in both disciplines,in order to initiate a dialogue between the
8、two groups that would further our knowledge and understanding of the cyclic deformation,of most specifically,nitinol-based medical devices and the physical environment in whichthey are expected to survive for considerable periods of time.The ultimate goal of thisinteraction is intended to?1?define t
9、he environments?i.e.duty cycle deformation-timehistories?in body-specific locations such as the superficial femoral artery,carotid,ab-dominal and thoracic arteries?2?develop constitutive expressions for the deformationresponse of nitinol via specific test methodologies and data analyses?3?develop th
10、eappropriate mechanics analyses for cumulative damage calculations and to ultimately?4?ascertain the fatigue lifetime of medical devices in the human body.To this end,stan-dards must be developed to define the subject matter listed above.ContentsOverviewviiPROCESSING,PROPERTIES AND ENVIRONMENTMartne
