TRUSTWORTHY PREDICTION OF BURSTING STRENGTH OF DUCTILE IRON PIPES BASED ON FITNET FSS CRITERION

A. Chennakesava Reddy

Abstract: The objective of the present work was to predict the bursting pressure of ductile iron pipes using Fitnet FSS criterion. The failure of the pipes was evaluated based on the Tresca and von Mises criteria. The significance of crack dimensions was recognized using Taguchi techniques. The highly influencing crack dimensions were pipe thickness and crack depth. The results obtained by the Fitnet FSS criterion have been in line with those of experimentation.
