Thermal gradients arising during transient regimes of start-up and shutdown operations produce a complex thermal and mechanical fatigue loading which limits the life of these components. This paper describes the application of TMF constitutive and durability models within Ford Motor Company. A unified elasto-visco-plastic constitutive model and a thermo-mechanical fatigue model developed by Sehitoglu et al. have been modified and implemented. The predictions of thermal strains and fatigue life based on three-dimensional FEA analysis are compared with measurements on engine component bench tests. Short biography: Dr. Carlos C. Engler-Pinto Jr. joined Ford Motor Company in August, 2001. He is technical expert in Materials Department and his interests include 1) material properties, specifically fatigue at elevated temperature (isothermal low cycle fatigue and thermo-mechanical fatigue testing and modeling); 2) statistical aspects of fatigue, fatigue at very high frequencies, and computer aided engineering (CAE). During his service at Ford, Carlos developed and implemented constitutive and fatigue life prediction models for power-train components (cylinder heads and exhaust manifolds). Carlos earned his bachelor degree in Universidade Estadual de Campinas (UNICAMP), SP, Brazil, in 1987, the master degree in Universidade Estadual de Campinas (UNICAMP), SP, Brazil, in1989, with the thesis title "Analysis of Fatigue Crack Retardation in 2024-T3 Aluminum Alloy Due to High-Low Block Loading" (in Portuguese) on, and his Ph. D degree in Laboratoire de Métallurgie Mécanique, Département des Matériaux École Polytechnique Fédérale de Lausanne, Switzerland, in 1996, with the thesis title "Study of Thermo-Mechanical Fatigue Damage of Nickel Base Superalloys" (in French). Carlos is fluent in Portuguese, English and French. He published and presented over 40 papers in international conferences and refereed journals.Carlos wasinvited as a Keynote Speaker in French Metallurgical Society Meeting, Paris, France (May 23-24, 2007). In2003, he received the Best Presentation Award in American Society of Testing Materials. In1997, he was invited speaker in Japan International Cooperation Agency-IPT meeting on Ni-Base Superalloys (May 03, 1997, São Paulo, Brazil). |
