Dan Adams President
Dr. Daniel O. Adams is president of Wyoming Test Fixtures Inc. (Salt Lake City, Utah, U.S.) and an emeritus professor of mechanical engineering at the University of Utah, where for 23 years he directed the Composite Mechanics Laboratory. He holds a B.S. in mechanical engineering and an M.S. and Ph.D. in engineering mechanics. Adams has a combined 44 years of academic/industry experience in the composite materials fi eld. He has published more than 120 technical papers, is chair of ASTM Committee D30 on Composite Materials and co-chair of the Testing Working Group for the Composite Materials Handbook (CMH-17). He regularly provides testing seminars and consulting services to the composites
industry.
