The Critical Compression Load for a Universal Testing Machine When the Specimen is Loaded through Knife Edges

Abstract

Theoretical and experimental investigations were conducted on a universal testing machine. Critical compression load is the load at which one loading head becomes laterally unstable in relation to the other. General equation is derived by which critical compression for any type of universal testing machine can be calculated providing load is applied through knife edges. Critical compression load was found to vary with specimen length. Shorter specimen results in machine's critical load being lower.
