Query: Space-time as strongly bent plate   Futher development is made of a consept of space-time as multidimensional
elastic plate, proposed earlier in [20,21]. General equilibrium equations,
including 4-dimensional tangent stress tensor - energy-momentum tensor of
matter - are derived. Comparative analysis of multidimensional elasticity
theory (MET) and GR is given. Variational principle, boundary conditions,
energy-momentum tensor, matter and space-time signature are reviewed within the
context of MET.
