Samenvatting

The plastic damage caused by multiple dynamic loading and its influence on the ductility and toughness of 3.5%Ni-steel (SA203E) and C-steel (SA516M) were examined for the discussion of integrity design of detonation chambers. Vnotched specimens and hourglass specimens were welded on 1/7-scale model of a 1-ton explosive class detonation chamber and subjected to 30 detonation shots. It has been indicated that 30 detonation shots caused pre-strain in the specimens. The ductility was reduced by the pre-strain. The Charpy impact toughness was affected as well in a lower temperature. It has been noted that the damage is developed with fatigue crack growth at notch root of the V-notched specimen.
