TALK=T;RUN(1,1) DISPLAY This problem is the same as that of s104; but nx is given a value greater than 1 as a test of capability, while nz retains its unity value. The stresses, strains and displacements should be independent of$ x. A long, hollow, thick-walled cylinder, immersed in an outer fluid, contains a second fluid having a different pressure. Since conditions vary with radius alone, nx and nz are set = 1 . Two constraints on its length are considered, namely: 1. the cylinder length may extend freely; and 2. the cylinder length may not extend at all. To enable the computed stresses and strains to be compared with theoretical (text-book) values, the latter have been computed. So as to make comparison easy, variables named P1/T etc have also been computed. They represent the calculated values divided by text-book ones. They should all be, and indeed are, close to 1.0; but zero is printed when the text-book value is zero Parameters which may be changed by editing this file include: (a) Material properties: Young's modulus and Poisson's ratio (b) Geometric quantities: inner and outer radius, and length. (c) Mechanical loadings: inner and outer pressures (d) The grid fineness (via NYCYL) (e) The grid-fineness distributions in x and y (via POWERX and POWERY) The text-book solution may be found in section 14.4 of Benham, Crawford and Armstrong, Mechanics of Engineering Materials; and also in Love's Mathematical Theory of Elasticity p144 .
