| Abstract |
Analytical and numerical methods are used to solve problems on the impact
of elastic and elastoplastic strikers of various configuration against an
absolutely rigid plane at a medium speed V0≤70 m/s (within small
strain theory). For elastic strikers, the stress in a typical cross-section
is computed for various orientations of the striker with respect to the
plane.
Earlier, problems on the impact of short flat elastic rods against a rigid
smooth obstacle were studied analytically in [1, 2], where striker recoil
and the accompanying loss of momentum due to the transition of part of the
rod energy to the energy of its transverse vibrations were analyzed. The
following problems were studied analytically and numerically in [3-5]: the
coaxial impact of a cylinder against a round plate (where good agreement
between the results the theoretical and numerical approaches was obtained)
and the problem on the recoil of a cubical striker from an absolutely rigid
plane.
We point out that the stress-strain state of strikers of various shape and
rheology, wave formation in them, and their recoil from obstacles were
studied by numerous authors (e.g., see [6-10]). In the present paper, an
attempt is made to reveal and study those aspects of striker theory which
are not reflected in papers of other authors. |
