Ted Belytschko

BS, PhD, Illinois Institute of Technology

Editor-in-Chief, International Journal for Numerical Methods in Engineering

Computational mechanics; finite elements and computer-aided engineering

Professor Belytschko is interested in computational methods for modeling the behavior of solids, with particular emphasis on failure and fracture. He has developed new meshfree methods and the extended finite element method for modeling arbitrary crack growth without remeshing and applied them to a variety of crack growth problems, both static and dynamic. He is also using molecular mechanics to study the fracture and behavior of nanotubes and developing methods for coupling heterogeneous subdomains, such as molecular and continuum models.
