How do I calculate the compression of a cylinder between flat parallel anvils? (FAQ - Length)

Formulae are given in Elastic Compression of Spheres and Cylinders at Point and Line Contact by M J Puttock and E G Thwaite (National Standards Laboratory Technical Paper No. 25, Commonwealth Scientific and Industrial Research Organization, Australia Melbourne 1969). This paper presents in a convenient form the formulae and data for the calculation of the compression effects which occur in the measurement and use of spheres and cylinders in dimensional metrology.

The NIST web site has a page that will automatically calculate compression for various cases encountered in engineering metrology ( - Search for 'Engineering Metrology Toolbox' - Select Elastic Compression and expand the Geometry branch of the tree).
