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 .
