We will focus on a sample that has been subjected to high-cycle fatigue. The fatigue test will be performed under constant maximum stress intensity, while the intensity range is continually decreased towards the end of the crack. The plastic zone size is expected to change as the intensity range drops. equipment_required: experiment: Dependence of Deformation zone size in Al2024 alloy on fatigue conditions foreign_nationals: Yun-Jo Ro (University of Virginia) (Already has access) hazards: instrument: 34ID-E microbeam instrument_other: minimumdays: 2 name: Judy Pang nonmembers: Sean Agnew (University of Virginia) Yun-Jo Ro (University of Virginia) unacceptable_dates: September 20-29 October 11-28 Note: Late Nov/Early Dec will be best z34ID_change_undulator: no z34ID_details: z34ID_parasitic: yes #REMOTE_HOST: pangj2k.ornl.gov #REMOTE_ADDR: 160.91.156.95 #CONTENT_LENGTH: 1061 #HTTP_REFERER: http://www.uni.aps.anl.gov/unireq.htm #HTTP_USER_AGENT: Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1)
