Evaluation of pile lengths using impact-induced flexural vibrations - A frequency domain approach

Non-destructive testing (NDT) techniques with impact-type excitations are often used to assess the dimension data of buried piles because such methods are generally simple in theory and relatively cost-efficient. For the evaluation of pile lengths, the feasibility of an approach relies on whether the influence due to reflected signals from the pile ends can be effectively detected and quantified. Both wave propagation theories associated with...
