Since the asymptote of the deformation is absent: n may be equal to 1 in (25). It is not hard to establish that in this very sim~le case (the load-relief wave of severe rupture is being propagated) dZ~/d~ < 0, i.e. in the absence of deformation distribution in the direct SWLR (see problem 2, property 2), the line el = el (x) is convex relative to the x axis. If a~,,/as,, ~-~, then the deformation distribution has a more complex form, caused by the possibility of the formation of a load-relief wave from the RSWLR.The author wczgd like to thank V. M. Kuzneteov for his attention to this work. LITERATURECITED
