Damage Detection in Steel Plates Based on Comparing Analytical Results of the Discrete 2-D Wavelet Transform of Primary and Secondary Modes Shape

Damage occurrence is always inevitable in structures. So far, many examples of damage types in engineering structures have been recorded with many losses of human and financial. For this reason, the detecting of structural damages during its exploitation to provide safety with the lowest cost has be...
