摘　　要：采用LS-DYNA动力学有限元软件对弹性体涂覆砌体墙在爆炸载荷下的响应进行了数值模拟,并研究了爆炸荷载作用下结构的应力、速度、位移的变化及破坏过程.通过比较各种涂覆方式下的响应,对该涂覆技术的有效性进行了评估.数值模拟的结果表明:采用弹性体涂覆能有效提高砌体墙的抗爆炸冲击能力.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.
