Simulation of Ductile Fracture Initiation in Steel Structures with Applications to Seismic Design
Special Warren Lecture in Honor of Robert Dexter
Gregory G. Deierlein
Civil and Environmental Engineering, Stanford University
ABSTRACT: This lecture summarizes recent research on continuum-based fracture mechanics, where cyclic void growth models are used to assess fracture initiation under large scale cyclic yielding. The models are implemented through finite element analyses and validated through a series of tests on notched axial bars, compact tension specimens, and large scale steel subassembly tests of braces and column base connections. Practical engineering applications are described.
