...S. T. Lie; Z. M. Yang This paper concerns on the development of numerical models for cracked square hollow sections (SHSs) T-, Y-, and K-joints. Based on these numerical models, the plastic collapse loads P c are calculated using nonlinear finite element method and through twice-elastic compliance...

... welds in cruciform, T, or lap joints under transverse loading failing by fatigue crack growth across the weld throat under normal stresses. The review covers the influence of residual stress, applied mean stress, joint fit-up and alignment, weld quality, the use of coated steel, the need for a plate...

...Mamdouh M. Salama Two failure modes were observed in tensile test specimens machined from TMCP steel pipe. Longitudinal centerline cracks were formed after necking followed by the conventional cup and cone transverse failure. The formation of the longitudinal cracks was attributed to sulfur...

...Naoki Fukuda; Naoto Hagiwara; Tomoki Masuda To investigate the mechanical properties of pipeline subjected to plastic deformation, tensile tests and crack-tip-opening displacement (CTOD) tests were conducted on X60, X65, and X80 line pipe steels with uniaxial tensile or compressive prestrain, ε pr...

...Ernesto Heredia-Zavoni; Roberto Montes-Iturrizaga A Bayesian framework is used for updating the probability distributions of the parameters of a fracture mechanics model and of crack size in tubular joints using information from inspection reports of fixed offshore structures. An error model...

... but the description of the time to crack initiation, crack growth law and probability of crack detection are updated using the information from the inspections. Its performance is demonstrated with a simulated example. The formulation presented in this paper is applied to the determination of the fatigue life...

..., including membrane stretching, local plastic bending, complex object geometry, rupture, cracking and friction. Advanced analytical formulas that can be used to describe these behavior mechanisms are introduced. These formulas are based on the advanced structural crashworthiness methodology. Recently, new...

...K. Y. Lam, Mem. ASME; Z. Zong; Q. X. Wang The failure of a cracked submarine pipeline subjected to the underwater explosion shock is probabilistically analyzed in this paper. A simple procedure is presented, in which the Monte Carlo method is used to estimate the bending stress distribution...

...Torgeir Moan; Ole T. Va˚rdal; Nils-C. Hellevig; Knut Skjoldli Observations made during more than 4000 in-service nondestructive examinations of tubular joints in North Sea jackets are utilized to determine the initial crack depth and probability of detecting (POD) cracks in magnet particle and eddy...

...David B. Lanning, Assistant Professor,; M.-H. Herman Shen, Mem. ASME, Associate Professor, This study investigates the reliability of a plate containing a semi-elliptical surface crack intersecting regions of dissimilar material properties. A weakest-link model is developed to express fracture...
