Fatigue Crack Growth Under Spectrum Loads
The Symposium on Fatigue Crack Growth Under Spectrum Loads was held on 23-24 June 1975 at the Seventy-eighth Annual Meeting of the American Society for Testing and Materials in Montreal, Quebec, Canada. Committee E24 on Fracture Testing of Metals and Committee E09 on Fatigue sponsored the symposium. R. P. Wei, Lehigh University, and R. I. Stephens, The University of Iowa, served as the symposium cochairmen. Serving as members of the Symposium Organizing/Program Committee and as session chairmen were J. M. Barsom, U. S. Steel Corp.; W. G. Clark, Jr., Westinghouse R & D Center; N. E. Dowling, Westinghouse R & D Center; C. M. Hudson, NASA Langley Research Center; E. K. Walker, Lockheed California Co.; and Howard Wood, AFFDL/FBR, Wright-Patterson AFB.
