| Summary: | Inspection tests for any manufactured structure are compulsory in order to detect the
existence of damage.It is to ensure the product integrity, reliability and to avoid further catastrophic
failure. In this research, modal analysis was utilizedto detect structural damage as one of the Non
Destructive Testing (NDT) methods. Comparingthe vibration signal of a healthy structure with a
non-healthy signalwas performed. A modal analysis of an adhesively bonded pipe joint was
investigated with a healthy joint as a reference. The damage joint was engineered by inserting a
nylon fiber, which act as an impurity at adhesive region. The impact test using hammer was utilized
in this research. Identification of shifting frequency of a free supported and clamped pipe joint was
performed.It was found that shiftingfrequency occurred to the lower side by 5%. |
