PRESSURE VESSELS - MIT
PRESSUREVESSELSD avid RoylanceDepartment of Materials Science and EngineeringMassachusetts Institute of TechnologyCambridge, MA 02139 August 23, 2001 IntroductionA good deal of the Mechanics of Materials can be introduced entirely within the confines ofuniaxially stressed structural elements, and this was the goal of the previous modules. But ofcourse the real world is three-dimensional, and we need to extend these concepts now take the next step, and consider those structures in which the loading is still simple, butwhere the stresses and strains now require a second dimension for their description.
Consider now a simple spherical vessel of radiusr and wall thickness b, such as a round ... Theaccuracy ofthisresultdependsonthevessel being“thin-walled,” i.e. r b.Atthe ... 10. What pressure is needed to expand a balloon, initially 3 in diameter and with a wall
