Abstract: Blast-resisitant doors are special structures. In orderto simulate the damage process and assess the safety of the doors, thedynamic effect, elastic-plastic deformation and contact between thedoor leaf and the doorframe, the hinges and the bearings should beconsidered. A certain series of blast-resistant doors are analyzed inthis paper with the finite element software of LS-DYNA. With the numerical method, 24 different load curves are analyzed tocover different kinds of loads that the doors may be subjected to.
