TL;DR: In this paper, the authors present formulas, charts, and background material that allow calculation of safety margins in ductile structures containing flaws, and extend the analysis procedures already available for brittle elastic materials to the tough and ductile steels used in the construction of pressure-boundary components.

Abstract: This report for RP1237-1 presents formulas, charts, and background material that allow calculation of safety margins in ductile structures containing flaws. It is intended as a reference book for engineers who are concerned with design and analysis of flawed structures. The work extends the analysis procedures already available for brittle elastic materials to the tough and ductile steels used in the construction of pressure-boundary components. These new elastic-plastic methods more accurately describe the behavior of ductile materials and show more tolerance to flaws than the elastic methods contained in the ASME Boiler and Pressure Vessel Code and the Code of Federal Regulations.

TL;DR: In this paper, the constitutive and equilibrium equations of the three types of elements utilized in the structure, namely, concrete, uniaxial steel and liner elements, are derived.

Abstract: A method of analysis of prestressed concrete pressure vessels subjected to pressure overload is presented. The method is based on the finite element variational procedure. A cracking criterion for concrete is discussed in detail. The steel elements are assumed to be elastic/ perfectly plastic. Von-Mises yield criterion and Prandtl-Reuss flow equations define the behavior of the liner in the range of plastic deformations. The constitutive and equilibrium equations of the three types of elements utilized in the structure, namely, concrete, uniaxial steel and liner elements, are derived. These equations are valid throughout the entire range of deformations. The case considered is one which involves two-dimensional (axisymmetric and plane) states of stress only. A step-by-step solution procedure, by which the pressure is applied incrementally is adopted. The utility of the method is demonstrated by an example; and a limited experimental correlation is given.

TL;DR: A survey of existing limit loads of structures containing defects is given in this paper, which is of use in performing a two-criterion failure assessment, in evaluating the J or C∗ parameters by the reference stress approximation, or in evaluating continuum creep damage using the reference stresses.

Abstract: A survey of existing limit loads of structures containing defects is given here. This is of use in performing a two-criterion failure assessment, in evaluating the J or C∗ parameters by the reference stress approximation, or in evaluating continuum creep damage using the reference stress. The geometries and loadings considered are (by section number): (2) single-edge notched plates under tension, bending and shear; (3) internal notches in plates under tension, bending and shear; (4) double-edge notched plates under tension, bending and shear; (5) short surface cracks in plates under tension and bending; (6) axisymmetric notches in round bars under tension and torsion, and chordal cracks in round bars under torsion and bending; (7) general shell structures; (8) surface/penetrating axial defects in cylinders under pressure; (9) surface/penetrating circumferential defects in cylinders under pressure and bending; (10) penetrating/short surface/axisymmetric surface defects in spheres under pressure; (11) penetrating/surface longitudinal/circumferential defects in pipe bends under pressure or bending; (12) surface defects at cylinder-cylinder intersections under pressure; (13) axisymmetric surface defects at sphere-cylinder intersections under pressure and thrust.

^{1}TL;DR: In this paper, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from a damping chamber via damping throttle in an injection event reaches the fillingpath of the pressure booster pressure chamber via the damped path.

Abstract: A fuel injection system for an internal combustion engine including a fuel injector which can be subjected to fuel at high pressure and is actuatable via a metering valve device by which the pressure in a pressure booster control chamber is controllable such that the pressure in a pressure booster pressure chamber, defined by a pressure booster piston, that can be filled with fuel from the high-pressure fuel source via a filling path in which a check valve is disposed and that is in communication with an injection valve member pressure chamber, is increased by the pressure booster piston such that an injection valve member opens for injecting fuel, whereupon fuel is positively displaced out of a damping chamber via a damping path, in which a damping throttle is disposed. To assure stable injection performance, the damping path is embodied such and connected in such a way to the filling path that the fuel positively displaced from the damping chamber via the damping throttle in an injection event reaches the filling path of the pressure booster pressure chamber via the damping path.
