O przestrzennych frontach fal naprężenia w izotropowym ośrodku sprężystym

The formulae have been derived for the shapes of spatial fronts of the stress waves propagating in soil and produced by a surface or air explosion of a nuclear charge. It has been demonstrated that the approximation used so far of those fronts by a single plane leads to tens of per cent errors, and in certain cases (high propagation speeds and deep subsite of structure) – to errors of hundreds of per cent.
