一个多世纪前，AA格里菲斯发表了开创性的论文，建立了断裂力学的基本框架。该理论创造性地将弹性能和表面能的概念引入断裂科学，解决了玻璃材料的脆性断裂问题。断裂力学中的许多后续里程碑式的研究都是由不同材料中遇到的真实的问题所激发的。二维（2D）材料的出现提供了一个令人兴奋的机会，检查在2D极限断裂过程。需要解决的一个重要问题是经典的格里菲斯理论是否仍然适用于二维材料。因此，本文将简要回顾二维材料断裂的实验和理论研究的最新进展，重点介绍相关技术和理论的新发展和新发现。鉴于探索二维材料断裂行为的早期阶段，更多的重点将放在这个萌芽领域的挑战和机遇上。图形摘要
More than a century ago, A.A. Griffith published the seminal paper establishing the foundational framework for fracture mechanics. The elegant theory creatively introduced the concepts of elastic energy and surface energy to the science of fracture, and solved the problem of brittle fracture of glass materials. Many subsequent milestone studies in fracture mechanics were motivated by the real problems encountered in different materials. The emergence of two-dimensional (2D) materials provides an exciting opportunity to examine fracture processes at the 2D limit. An important question to be addressed is whether the classic Griffith theory is still applicable to 2D materials. Therefore, recent progress in both experimental and theoretical studies of fracture of 2D materials will be briefly reviewed, with new developments and discoveries in relevant techniques and theories highlighted. Given the early stage of exploring fracture behaviors in 2D materials, more emphasis will be placed on challenges and opportunities for this budding field. Graphical abstract
