Abstract 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.

由新型联锁砖制成的板状组件的冲击行为：一项实验研究

摘要 在本文中，我们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，具有四个凹凸侧面，用于互锁。已经进行了落锤试验，通过施加不同水平的冲击力和侧向限制载荷来研究互锁装配板的机械响应。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具有显着提高的抗弯性能。在冲击过程中，单个砖块的断裂总是沿着由互锁砖块的几何约束确定的载荷传递路径发生。最重要的是，
