E XPERIMENTAL ARRANGEMENT FOR THE VALIDATION OF RESULTS FROM THE ADAPTIVE CLONAL SELECTION ALGORITHM

T

he experimental arrangement developed of a cantilever beam. Various experiments or tests are done using different crack geometries were taken. From the various tests the first three modal frequencies of the vibration signature were collected. The dimensions of the cantilever beam considered for experimental analysis are 800x38x10. Instruments used in the experimental analysis are given below:
