By using piezoelectric actuator bridge can be accelerated locally to detect the
effect of small damage like fatigue crack as a response change of vibration.
Transfer function (TF) of the vibration response can give us the indication of
existence of damage before and after the damage. Detail analysis of TF before
and after damage can inform us location and size (area) of damage. This paper
shows the result of numerical analysis of damage detection on beam member by
using local force excitation method.
