The Stress State Identification of Critical Bridge Components Using Nonlinear Acoustics

TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) program Report 158: The Stress State Identification of Critical Bridge Components Using Nonlinear Acoustics has released a report that examines the application of a nonlinear acoustics-based technique for identifying the stress state of critical highway bridge components through laboratory-scale and field testing.
