Abstract
AbstractIn order to study the anti-detonation performance of welded joint structure of armored steel, the finite element analysis of welded joint structure under explosion impact was carried out by using material assignment method and structured ALE algorithm (S-ALE), and the accuracy of the model was verified by explosion impact test. The central deformation and failure form of each weld structure under different equivalent loads of a single explosion are studied. Repeated explosive loading of weld structure based on complete restart technology; The cumulative analysis of plastic deformation of weld structure under multiple explosions is realized, and the relationship between central deformation and explosion times and explosion equivalent is obtained.
