本文研究了作者最近提出的一种新型联锁砖。砖具有对称的几何形状，具有用于互锁目的的四个凹凸侧表面。通过落重试验研究了联锁组合板在不同水平冲击力和侧向约束荷载作用下的力学响应。结果表明，与整体板相比，新型联锁装配板在冲击能量吸收能力方面的抗弯性能有显着提高。在冲击期间，单个砖的断裂总是沿着由互锁砖的几何约束确定的载荷传递路径发生。最重要的是，板状组件的联锁设计可以有效地防止裂缝的传播和蔓延，使单个砖的损坏不会导致整个结构的灾难性故障。
In this paper we study a new type of interlocking brick recently proposed by the authors. The brick has a symmetrical geometry with four concavo-convex side surfaces for the interlocking purpose. Drop weight tests have been conducted to investigate the mechanical response of interlocking assembly plates by applying different levels of impact force and lateral confining load. The results show that, compared with monolithic plates, the new interlocking assembly plates have significantly improved flexural performance in terms of impact energy absorption capacity. The fracture of individual bricks during the impact always occurs along a load transmission path that is determined by the geometrical constraints of the interlocking bricks. Most importantly, the interlocking design of the plate-like assembly can effectively prevent the propagation and spread of the cracks, so that the damage to a single brick will not lead to a catastrophic failure of the entire structure.
