In order to investigate the behavior of wire under the dynamic load, the authors experiment with a drop hammer type apparatus and the observed experlmental results, that is, stress-strain diagrams, dimension effect, and breaking stress etc., are compared with those of statics. The authors made the numerical calculations on the base of Ludwik's law, which was obtained by the test at a constant strain-rate, and calculated stresses are compared with those of experlment. The numerical calculations seem comparatively good agree with experimental results.
