The study contains a theoretical and experimental evaluation of the mechanical behavior of wires in a flexible (“Euler”) test probe, including buckling, axial and lateral deflections and stresses. The developed formulas are simple, easy-to-use and clearly indicate the role of the major factors affecting the wire performance. Calculations, executed for an Everett-Charles 32 point probe, are in good agreement with the measured data. Some recommendations for smaller stresses in the wires are presented. The obtained results could be of help in the analysis and physical design of “Euler” test probes.
