Special features in convergence dynamics of steel shells under their explosive loading. Results of laser-interferometric measurements
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 R HE =...

Summary: | 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
R
HE
= 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. |
