| Abstract: | The dynamic responses of the elastomer-coated masonry wall under blast loading are simulated with the finite element explicit hydrocode LS-DYNA. The dynamic responsive characteristics including stress, velocity, displacement and failure process are studied. The validity of the proposed coating technique is evaluated by comparing the responses of masonry wall with different coating conditions. It indicates that the structure performance under blast loading is clearly improved with the elastomer coating. |
