Viggo Tvergaard is a Professor Emer. of Solid Mechanics at the Technical University of Denmark. He got his Ph.D. in 1971 from the Technical University of Denmark, and his dr. techn. degree in 1978.
His primary research interests are instabilities of structures and solids, the mechanics of materials, fracture mechanics, damage mechanics, and micromechanics. Post-buckling behavior of structures, and tensile instabilities at large plastic strains have been studied. Also the micromechanics of damage has had much focus, including ductile fracture models, the micromechanics of intergranular creep damage, metal-ceramic systems, cohesive zone representations, and the mechanics of polymers.
Since 1995 he is the Editor-in-Chief of the European Journal of Mechanics A/Solids. He is a foreign member of Royal Netherlands Academy of Arts and Sciences, and of the US National Academy of Engineering, and is an honorary member of ESIS, Eur. Struct. Integrity Soc. He was appointed Visiting Professor of Engineering at Brown University 1989-94, obtained an Honorary Doctor Degree from the Royal Institute of Technology, Stockholm, Sweden, 1993, received the 1998 Koiter Medal of ASME, and the 2009 Euromech Solid Mechanics Prize. Has published more than 330 international scientific articles. President of IUTAM from 2012 to 2016, now Vice-President of IUTAM.
