Biography
Benjamin Spencer brings his computational solid mechanics expertise to the Bison development effort. He has broad experience developing and applying computational methods for fracture, contact, constitutive modeling, and structural dynamics in massively parallel computing environments. Prior to coming to INL in 2011, he worked at Sandia National Laboratories, where he developed implicit and explicit solid mechanics codes and simulated nuclear safety-related structures subjected to a variety of natural and man-made insults. He received his Ph.D. in Civil Engineering from the University of Colorado at Boulder in 2002.
