The Crack Injury Detection Based CMR and Natural Frequency with BP Neutral Network
In this paper a new approach based curvature mode ratio (CMR) and natural frequency with BP neutral network for crack injury detection is proposed. Taking a simple cantilever beam with multiple damage and perfect structure as study object, injury indices are gained by way of analysis the merit and drawback of natural frequency and the curvature mode, then use BP neutral network training tests that regards the natural frequency, the amount of the frequency relative decline and the first-order maximum CMR as the input parameter, crack location and injury degree as the output parameter. The simulated results confirm that the method can be very well applied to the crack damage identification.
