DAMAGE DETECTION IN SIMPLE SUPPORTED PIPE CONVEYING FLUID USING AN ADDITIONAL MOVING MASS

Resumo

This paper investigated the dynamic behavior a cracked simple supported pipe conveying fluid due to
the application of an additional roving mass along the structure. First, a difference finite model of a simple
supported Euler-Bernoulli beam conveying fluid experimental was developed to obtain natural frequencies of
damped modal analysis. The results are compared to literature. In addition, the frequency shift technique is applied
for an undamaged simple support pipe conveying fluid. Last, it was identified a cracked simple supported pipe
using a frequency shift technique for different fluid velocity.
