I have a thick wall, steel shell (cylinder) with two internal seal grooves. These grooves are stress risers. Now the literature specifies a stress decay distance of k x square root of (R x t) for various types of discontinuities. The value of k used varies from Pi/2 to Pi/4 to 1.0 to 0.5 and...
I am involved in the analysis and design of a suspension systemfor a heavy duty vehicle (oilfield). For the purposes of preliminary design I am hopeful of obtaining a rough road spectrum. Possibly, something Federal (public domain). I thought that the Army or the DOT might publish something...
I am trying to determine the maximum deflection for a thick, rectangular, flat plate with a central opening and annular line load about the opening. The support is fixed along the two short edges.
I have made literature search for an already developed equation that fits this case, and haven't...
I need to calculate the force required to indent slip teeth into pipe od to a given depth of a few thousandths of an inch (variable). It is a plastic-flow problem that so far eludes me. The teeth are much harder than the pipe and the pipe is ductile steel. Strain hardening need not be...
Since API-6A, BX type ring gaskets, first contact the ring groove with a initial standoff of approximately 1/8-inch, how do I determine the bolt load necessary to bring the flange faces into contact, as required for this type connection. We are having trouble accomplishing face to face contact...
I have looked high and low for journal papers etc. with little luck.
In order to design a coiled-tubing reel one needs to calculate the applied loads. For a given tube size/material, tube tension, number of layers, and core radius, how may the normal spreading loads and radial compressive...
