Dynamics of hybrid hardening and viscoplastic beams under explosive effects
We consider polymetallic beams of constant cross-section from sets of hardening and viscoplastic materials with their two-symmetric arrangement in the cross-section. The beams are considered to be subject to explosive loads. For all materials, a rigid-viscoplastic deformation model was used and the classical Kirchhoff deformation hypotheses were adopted. For bimetallic hinged- supported beams, general equations of deformation are obtained and a method for their solution is described. Residual forms of dynamic damage were determined.
