Edward M. Wu

from Wikipedia, the free encyclopedia

Edward Ming-Chi Wu ( September 30, 1938 - June 3, 2009 ) was an American engineer. He is best known for the Tsai-Wu criterion developed by himself and Stephen W. Tsai .

Life and research

Wu has worked at Washington University in St. Louis , Missouri, the Lawrence Livermore National Laboratory of the University of California, and the Naval Postgraduate School in the Department of Aeronautics and Astronautics in Monterey .

In research today, Wu and Stephen W. Tsai represent the most widespread strength criterion for fiber-plastic composites , known as the Tsai-Wu criterion for short . It is implemented in the majority of all calculation programs available worldwide for component design with these materials. One advantage is the mathematically simple polynomial formulation of the criterion and the possibility of adapting the criterion to different test results. However, it is disadvantageous that it is not possible to differentiate between the basic failure types fiber breakage (Fb) and inter-fiber breakage (Zfb), despite some interpretations in the literature. The interaction coefficient and the overestimation of the compressive strength also cause difficulties .

A comparison with other strength criteria for fiber-plastic composites can be found in the extensive World-Wide Failure Exercise .
