Professor Needleman’s main research interests are in the computational modelling of inelastic deformation and fracture in structural materials, in particular metals.
A general objective is to provide quantitative relations between the measurable features of the materials’ micro-scale structure and its macroscopic mechanical behaviour. Ongoing research projects involves studies of ductile fracture and ductile-brittle transitions, crack growth in heterogeneous microstructures with particular emphasis on the role of interfaces, nonlocal and discrete dislocation plasticity, dynamic fracture.
Professor Needleman is a member of the American National Academy of Engineering, a Fellow of the American Society of Mechanical Engineers, a Fellow of the American Academy of Mechanics, an Honorary member of MECAMAT (Groupe Français de Mécanique des Matériaux) and a Foreign member of the Danish Center for Applied Mathematics and Mechanics.
He has been recognized by ESI as a highly cited author both in Engineering and Material Science.
In 1977 he was a Guggenheim Fellow, and in 2006 he received a doctor technices honoris causa from the Technical University of Denmark, Copenhagen,the Prager Medal from the Society of Engineering Science and the Drucker Medal from ASME.
