Approximate methods for predicting J-integral of a circumferentially surface-cracked pipe subject to bending
This study proposes two new methods to estimate the energy release rate of a circumferentially cracked pipe with an internal, constant-depth, finite-length surface flaw subjected to pure bending loads. The methods are based on the deformation theory of plasticity, constitutive law characterized by Ramberg–Osgood model, and an equivalence criterion incorporating reduced thickness analogy for sim...
متن کاملNumerical Analysis of explosion effects on the redistribution of residual stresses in the underwater welded pipe
Structural health monitoring of cracked structures is one of beloved subject of researchers recently. Consider of crack behavior in the water and energy pipeline is important because of environmental problems. In this paper consider of crack parameters in the underwater pipe subjected to mechanical transient load is investigated. For this purpose, three- dimensional parametric model of cracked ...

متن کاملA novel boundary integral equation for surface crack model
A novel boundary integral equation (BIE) is developed for eddy-current nondestructive evaluation problems with surface crack under a uniform applied magnetic field. Once the field and its normal derivative are obtained for the structure in the absence of cracks, normal derivative of scattered field on the conductor surface can be calculated by solving this equation with the aid of method of mom...
متن کاملPrediction of the Crack Kinking in a Sandwich Composite Beam Subjected to Three Point Bending Using the J Integral Concept
Composite materials utilizing the sandwich structure are a basic family of materials and possess a highly increasing use in modern industrial applications. Since the traditional approach to structural design and material selection tends to be replaced by the Fracture mechanics approach, it is worth understanding the way that the Fracture mechanics approach is applied. The traditional approach t...
