“…(1). Moffat and Mistry (1988) also obtained a similar quadratic interaction from their experimental findings for large diameter branches with (d/D) = 0.5 and 1. The work by Lynch et al (2000) involved elastic-perfectly-plastic FE analyses to evaluate the interaction diagrams of three piping tees (d/D = 0.5, t/T = 1.0 and D/T equal to 10, 20 or 30, respectively) with and without cracks under the effect of combined out-of-plane bending with varying level of internal pressure.…”

“…The behavior of defect free piping branch junctions has been studied in some detail by Jiang (1984) in China, Moffat and Mistry (1988) in UK and Rodabaugh and Moore (1978) in USA. The limited existing knowledge on tees or nozzles in cylindrical shell with cracks in them has been catalogued in the reviews by Xuan et al (2000) and Miller (1988).…”

A specialized shell-intersection finite element, which is compatible with adjoining shell elements, has been developed and has the capability of physically representing the complex three-dimensional geometry and stress state at shell intersections (Koves, 1993). The element geometry is a contoured shape that matches a wide variety of practical nozzle configurations used in ASME Code pressure vessel construction, and allows computational rigor. A closed-form theory of elasticity solution was used to compute the stress state and strain energy in the element. The concept of an energy-equivalent nodal displacement and force vector set was then developed to allow complete compatibility with adjoining shell elements and retain the analytical rigor within the element. This methodology provides a powerful and robust computation scheme that maintains the computational efficiency of shell element solutions. The shell-intersection element was then applied to the cylinder-sphere and cylinder-cylinder intersection problems.
