- Tapered cantilever beams are widely used as machine elements and structural elements in mechanical, naval, civil, aeronautical engineering. There are unexpected sudden failures on machine elements. In order to attain maximum reliability of machine and structure, so the best way is to monitoring the health of susceptible critical component.Cracks are the most encountered damage types in the structures due to fatigue or manufacturing defects. Cracks found in structural elements may fail the whole system. Natural frequencies of structures are measured most easily and accurately. Experimental Modal Analysis (EMA) was performed on cracked beams and a healthy beam using ANSYS 18.1. In the inverse analysis, detect the location and size of a crack by providing the natural frequencies as inputs. The first three natural frequencies were considered as basic criterion for detection of crack size and location. Compare the experimental and EMA results for validate the method adopted.
