| Abstract: | The gap element method is used to analyse two-dimensional elastoviscoplastic contact problem of circular tubes under explosive welding for the first time.The process of explosive welding of circular tubes is analyzed in detail. The lower limit of explosive pressure in an engineering problem is given. It is very useful o engineering applying. |
