摘要：

In this note a method for prediction of location and size of a crack based on measurements of natural frequencies has been verified experimentally considering taper and segmented cantilever beam geometries. The analysis is based on the concept of a rotational spring to represent the crack section and the Frobenius method to solve differential equation with variable coefficients. The crack size is computed using a relation between stiffness and crack size. The maximum error in predicting the crack locations is 8%. The maximum error in predicting the crack size is 20%.
