Plastic Deformation Analysis of a Damaged Ship Under Non-contact Explosion

摘要

The plastic deformation of hold section of a warship subjected to noncontactexplosion pressure caused by an anti-ship missile or a laserguidedbomb was analyzed in this paper . The explosion load istransformed to static load on the basis of explosion theory and somecorrespondence literatures. Both nonlinear material and nonlineargeometrical are considered in the finite-element analysis. Thecorrespondence conclusions about the compartment attacked by an antishipmissile or a laser-guided bomb were obtained.
