Popis:	The Fabry-Perot laser-interferometric diagnostics and the recovery method were used to study features of the convergence dynamics for high-radii shells of hardened 30KhGSA steel (HRC 35–40) and austenitic stainless 12Kh18N10T steel in the spherical explosive systems having the external radii RHE = 40 and 110 mm. The experiments helped us to determine loading conditions that cause the following modes of convergence in steel shells: spall-free convergence, spall convergence with the closure of the spall with the main part of the shell, spall convergence without closure of spalls.
