      The calculation of ground mot-ion generated by a punch covered with a thin cylinder shell is studied. Direct solution of such a problem using the VULCAN finite-difference scheme is shown to be cost-ineffective. It is proposed to replace the shell by a normal stress boundary condition resulting from an analysis of a thin elastic-plastic shell behavior under loading.
