The effect of progressive crack on dynamic properties of tapered beam using EMA / Mohd Hafiz Zaini

Cracks in vibrating component can initiate catastrophic failures. The presences of cracks change the physical characteristics of a structure which in turn alter its dynamic response characteristics. Therefore there is need to understand dynamics of cracked structures. Crack depth and location are th...
