| Abstract: | The process of kinematic braze-welding of thin-walled tube plates and tubular elements in making heat exchangers is considered. The process is simulated by the high-velocity contact interaction of coaxial cylinders with a thin layer of high-strength amorphous solder between them. The inner cylinder expands by the action of explosive pulse load. When solving the thermoelastoplasticity problem, the dynamic properties of the material are taken into account. This process has been experimentally investigated using test specimens. |
