Experimental measure and model validation of COD of cracked pipes under bending

Update: 2013-07-10

Description

In order to apply the “Leak Before Break” (LBB) Analysis is very important to know the cracks area. Particularly for pipes under bending the area depends from crack position related to the bending plane.
Considering symmetrical cracks respect to the flexural plane cannot be a conservative assumption. In this work has been carried out an experimental investigation in order to evaluate COD distribution for off-axis cracks on pipes under bending. Have been tested pipes with different thickness and different cracks lengths and orientations. COD distribution has been monitored by digital image correlation (DIC). Experimental data have been used to validate an analytical model (HCM Hodograph Cone Method) previously proposed by the authors.
