However, when the applied stress exceeds the ultimate strength limit of bamboo scrimber, cracks occur, which affects the performance of bamboo scrimber in structural applications. Due to the propensity of cracks to propagate, it reduces the load-bearing capacity of the bamboo scrimber material. Therefore, research on the fracture toughness of bamboo scrimber contributes to determining the material\u2019s load-bearing capacity and failure mechanisms, enabling its widespread application in engineering failure analysis. The fracture toughness of bamboo scrimber was studied via the single-edge notched beam (SENB) experiment and compact compression (CC) method. Nine groups of longitudinal and transverse samples were selected for experimental investigation. The fracture toughness of longitudinal bamboo scrimber under tensile and compressive loadings was 3.59 MPa\u00b7m1\/2 and 2.39 MPa\u00b7m1\/2, respectively. In addition, the fracture toughness of transverse bamboo scrimber under tensile and compressive conditions was 0.38 MPa\u00b7m1\/2 and 1.79 MPa\u00b7m1\/2, respectively. The results show that, for this material, there was a significant distinction between longitudinal and transverse. Subsequently, three-point bending tests and simulations were studied. The results show that the failure mode and the force\u2013displacement curve of the numerical simulation were highly consistent compared with the experimental results. It could verify the correctness of the test parameters. Finally, the flexural strength of bamboo scrimber was calculated to be as high as 143.16 MPa. This paper provides data accumulation for the numerical simulation of bamboo scrimber, which can further promote the development of bamboo scrimber parameters in all aspects of the application.<\/jats:p>","DOI":"10.3390\/ma16134880","type":"journal-article","created":{"date-parts":[[2023,7,10]],"date-time":"2023-07-10T00:54:23Z","timestamp":1688950463000},"page":"4880","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Experimental Study on the Fracture Toughness of Bamboo Scrimber"],"prefix":"10.3390","volume":"16","author":[{"given":"Kairan","family":"Zhang","sequence":"first","affiliation":[{"name":"School of Advanced Manufacturing, Fuzhou University, Fuzhou 350108, China"},{"name":"Quanzhou Institute of Equipment Manufacturing, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Quanzhou 362216, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yubo","family":"Hou","sequence":"additional","affiliation":[{"name":"Quanzhou Institute of Equipment Manufacturing, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Quanzhou 362216, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yubin","family":"Lu","sequence":"additional","affiliation":[{"name":"Quanzhou Institute of Equipment Manufacturing, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Quanzhou 362216, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mingtao","family":"Wang","sequence":"additional","affiliation":[{"name":"Quanzhou Institute of Equipment Manufacturing, Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences, Quanzhou 362216, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,7,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"15","DOI":"10.1016\/j.conbuildmat.2021.124258","article-title":"Tensile mechanical properties and failure mechanism of bamboo scrimber under different strain rates","volume":"299","author":"Wang","year":"2021","journal-title":"Constr.
