A Thin Cylinder Problem.
Abstract
A test problem was required for the evaluation of the computer aided design (CAD) system, which is currently being purchased by Benet Weapons Laboratory. We needed a relatively simple finite element stress anlaysis problem which could easily be done on a CAD system, by the potential contractor, to demonstrate a particular system. The geometry selected was a simple thin cylinder of mean radius 1.0 subjected to an axial tension load. The load is distributed at the ends of the cylinder to produced a uniform unit (1.0) nominal stress. The cylinder is 3 PI (9.4278) long and contains a single perforation at mid-length, in the form of a circular hole of radius 0.15. The problem is to find the stress concentration factor (S.C.F.) for the hole when the thickness of the cylinder is 0.0143525. The most desirable solution is for a shell formulation with membrane and vending stiffness terms. Along with the S.C.F., it is also desirable to generate the following graphic output: (1) A deformed structure plot; (2) A maximum principal stress contour plot on the inside surface; and (3) A maximum principal stress contour plot on the outside surface. If necessary, the problem may be reduced to a membrane problem with only one contour plot.
