Strain waves in an elastoplastic rod under longitudinal impact

  • V. A. Kotlyarevskii
Scientific-Technical Section


  1. 1.

    Dimensional analysis indicates that for impact with a sufficiently large (dimensionless) mass of striker (m ∼ 105) the nature of strain inhomogeneity for elastoplastic chromium steel specimens weakly sensitive to strain rate is governed by parameter V.

  2. 2.

    In order to provide a strain regime close to a quasistatic one, it is recommended that for V < Vt a tolerable limiting value of Vt = 0.04 be adopted.
