First, the geometry and material properties of the specimens are briefly introduced, followed by a detailed description of the shell finite element-based model. The model is then validated against recent test data, showing good agreement with experimental failure modes, load-deflection responses and strain distributions, thereby demonstrating its accuracy and reliability. Finally, the validated model is used to systematically explore the influence of some key parameters that have not been thoroughly studied or have never been examined, namely the threshold distance between loaded and support sections (<em>D</em>), web slenderness (<em>H</em>/<em>t</em>), flange restraint, and bearing plate material. The study of these parameters aims to provide valuable insights for future design and engineering applications. The results indicate that web slenderness, flange restraint and FRP plate thickness have a significant impact on resistance and failure patterns; in particular, flange restraint increases load capacity by up to approximately 42 % under EOF and 24 % under IOF conditions, depending on the bearing length. In addition, a more appropriate parameter for defining the threshold distance was found to be the web slenderness ratio (<em>H</em>/<em>t</em>). For the geometries of GFRP profiles currently available on the market (with web slenderness, <em>H</em>/<em>t</em> = 152 mm/6.3 mm ≈ 24.1), it is recommended that no threshold distance be defined, at least in the case of internal flange loading.</div></div>","PeriodicalId":10660,"journal":{"name":"Composites Part B: Engineering","volume":"307 ","pages":"Article 112915"},"PeriodicalIF":14.2,"publicationDate":"2025-08-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144889423","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this context, this research aims to investigate the crashworthiness performance of 3D-printed polylactic acid (PLA) structures integrated within circular aluminum (Al) tubes. Special emphasis is placed on examining the influence of 3D printing parameters under quasi-static lateral loading conditions. To achieve this, three key printing parameters were each evaluated at four distinct levels: the infill pattern (gyroid, honeycomb, Schwarz P, and Schwarz D), infill density (5, 10, 20, and 30 %), and layer height (0.15, 0.20, 0.25, and 0.30 mm). Throughout this process, the data were systematically collected on the crash force, energy absorption, and displacement responses. Moreover, failure histories were recorded for each tube, offering insights into the structural failure progression and characteristics.
