On the explosive welding of a ring to the axisymmetric body

The paper deals with the evaluation of the explosive welding of a ring to t he axisymmetric steel body (projectile). The two experimental methods (Hopk inson Split Pressure bar and Taylor Test) were used for the determination o f the constitutive equations of materials of ring and body. These equations , together with the equations describing the damage development, were used in three-dimensional finite element code. This code also enabled simulation of the explosion detonation process. The computed pressure-time history ag reed well with experimental ones. The results of the numerical simulation w ere compared with experimental ones. The field experiments, i.e. the behavi our of the whole body during the launching, confirmed the very good quality of the given joining (ring-body). (C) 1999 Elsevier Science S.A.
