Professor Diana Lados is Assistant Professor of Mechanical Engineering and Director of the Integrative Materials Design Center (iMdc) at Worcester Polytechnic Institute (WPI). She received her B.S./M.S in Mechanical Engineering from Polytechnic University of Bucharest in 1997, her second M.S. in Mechanical Engineering from Southern Illinois University in 1999, and her Doctorate in Materials Science and Engineering from WPI in 2004. After graduating from WPI, she worked as a Post-Doctoral Research Scientist and Research Professor at the Metal Processing Institute (MPI) for over two years, and is now part of the faculty of the Mechanical Engineering Department at WPI.

After joining a tenure-track post at WPI, Professor Lados has initiated iMdc, an industry/government-university alliance dedicated to advancing the frontiers of sustainable materials/process design and manufacturing for reliability and high-performance with significant emphasis on life-cycle engineering, green processing, and recycling. Lados’s research interests and expertise are in materials processing and mechanical behavior of materials with focus on failure prevention and increased reliability and recyclability. She is credited with significant research contributions in the areas of fatigue, fatigue crack growth, and fracture of engineering materials, including light metal alloys and composites, powder metallurgy steels, as well as work on physical metallurgy aspects of solidification processes and post-processing operations of cast alloys, green manufacturing, microstructure characterization, microstructure-performance relationships, residual stress, plasticity, and fracture mechanics.

For her accomplishments, Professor Lados has been distinguished with several national and international honors and awards. These include finalist in the Bodycote Paper Prize Competition, 2004, UK; Center for Powder Metallurgy Technology - CPMT/Axel Madsen Award, 2003; Sigma Xi Graduate Research Scientific Award - Ph.D. Award, 2001; American Foundry Society - Aluminum Division Scholarship Award, 2000; ASM Chet Inman Award, 1999 - 2000; Best Graduating Student Award, 1997 (Student of the Year Award - Polytechnic University of Bucharest); 1st Prize - Scientific Session Contest, Bucharest, 1996.

Professor Lados has over 40 publications and 80 technical presentations in Materials Science and Mechanical Engineering. She is a member of various professional societies including Sigma Xi, TMS, ASM, AFS, AcerS, AIST, ASTM, MPIF, Who’s Who in Science and Engineering, Manchester Who’s Who Among Executives and Professionals Women in Research and Science, Who’s Who in Powder Metallurgy. She is the 2007-2008 Chair of ASM International - Worcester Chapter. She serves since 2004 on the Board of Review for ASM-TMS/Metallurgical and Materials Transactions A & B (Exemplary Service Award as a Key Reader - January 2006) and is an active member of ASTM organizing committees. She is also a reviewer for journals in Materials Science and Mechanical Engineering such as Acta Materialia, Materials Science and Engineering A, International Journal of Fatigue, International Journal of Fracture, Engineering Fracture Mechanics, Materials Science and Technology, Journal of Alloys and Compounds, Microporous and Mesoporous Materials.

Professor Lados is a firm believer and a devoted advocate of a new design philosophy based on material-process-component integration. She is consistently promoting this design paradigm through her research and disseminating it through publications, presentations, panel discussions, and lectures at national and international conferences, workshops, professional group meetings, internal corporate meetings. Her integrative design research has built connectivity within the field of Materials Science and interdisciplinary bridges between Materials Science and Mechanical Engineering. Industrial corporations such as General Motors, Mercury Marine, Alcoa, Alcan, NASA, Lockheed Martin, Boeing, Pratt and Whitney, Hamilton Sundstrand, Air Force, PANalytical, Fracture Technology Associates as well as ASTM standards such as E647 use the knowledge and the techniques developed by Professor Lados for advanced materials/process design and sustainable manufacturing.

Research Students


Anastasios G. Gavras

Ph.D. Student, iMdc
+1-508-736-1026; angavras@wpi.edu
WB 333
B.S., National Technical University of Athens, 2006
M.S., National Technical University of Athens, 2007

Surface properties - corrosion, adhesion, and wear; fatigue and fatigue crack growth behavior of metallic and composite materials; materials processing; materials/process design for high-integrity applications.

Mr. Gavras received his B.S. in Mining Engineering and Metallurgy in 2006 and his M.S. in Materials Science and Engineering in 2007 from National Technical University of Athens. After graduating from the National Technical University of Athens, he joined the Integrative Materials Design Center (iMdc) at WPI in January 2008.

During the B.S. and M.S. programs, his research was focused on surface properties - corrosion and wear of Al-Si-Mg wrought alloys and corrosion and adhesion behavior of composite coatings on mild steel substrates.

His current research addresses fatigue and fatigue crack growth mechanisms of wrought and cast alloys used for high-integrity automotive, aerospace, marine, and military applications with emphasis on microstructural effects and processing conditions. Fracture mechanics principles and their correlations to materials microstructures are also important considerations in Mr. Gavras's research while implementing this interdisciplinary knowledge into a new structural design approach.


Christopher J. Lammi

M.S. Student, iMdc
+1-508-831-5898; cjlammi@wpi.edu
HL 301
B.S., Physics, University of Massachusetts, Amherst

Residual stress; fatigue crack initiation and propagation in the presence of residual stresses; residual stress measurement and correction; interaction of residual stress with ultra-fine (nano sized) microstructures; materials processing; materials/process design for high-integrity applications

Mr. Lammi received his B.S. in Physics in 2005 from The University of Massachusetts in Amherst, MA. After graduating from The University of Massachusetts, he spent two years working in the photonics industry for Axcel Photonics, Inc., a manufacturer of semiconductor lasers. In the fall of 2007, he began his Master's Degree work at WPI, and shortly thereafter joined the Integrative Materials Design Center (iMdc) at WPI in December 2007.

During Mr. Lammi's B.S. program, his research was focused on the production of metallic nanowires via electrodeposition within chemically etched nuclear tracks in thin polycarbonate films.

His current research addresses fatigue and fatigue crack growth mechanisms of wrought and cast alloys used for high-integrity structural applications with emphasis on residual stress, fatigue crack growth in residual stress fields, processing effects on residual stress, and residual stress measurement. Chris's research addresses residual stress through experimental, analytical, and numerical perspectives and integrates fracture mechanics considerations in corrective models for residual stress compensation in design.
