Free Vibration Analysis for Dynamic Stiffness Degradation of Cracked Cantilever Plate

In the present work a dynamic analysis technique have been developed to investigate and characterize the quantity of elastic module degradation of cracked cantilever plates due to presence of a defect such as surface of internal crack under free vibration. A new generalized technique represents...
