To develop a mathematical model, two different higher-order displacement kinematics, Green-Lagrange’s nonlinear strain–displacement relations and two sub-laminate approaches are adopted for delaminated panel structure in association with finite element steps. The delaminated composite shell panel is under the three simultaneous loading, i.e., humidity, temperature, and mechanical loading. The nonlinear time-dependent responses are obtained by solving the governing equation using the direct iterative method and Newmark’s integration technique. The influence of delamination parameters (size, location, and position), geometry and loading on dynamic characteristics have been analyzed. The differences in responses indicated that the kinematic model with higher degrees of freedom generally shows higher deflection values. Further, a detailed discussion of the numerical illustrations and conclusive remarks based on the findings of the numerical illustrations have been provided.</div></div>","PeriodicalId":282,"journal":{"name":"Composites Part A: Applied Science and Manufacturing","volume":"189 ","pages":"Article 108587"},"PeriodicalIF":8.1,"publicationDate":"2024-11-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142703518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

An exact elastic analysis shows that the displacement gap on the delamination crack surfaces does not enter the stiffness expressions explicitly. The delamination affects the stiffness via larger COD and CSD of the intralaminar crack. This means that the same expressions for cracked laminates with and without delaminations can be used but with different expressions for COD and CSD. Finite element method is used to analyze the CSD dependence on delamination length and crack density. The obtained approximative expressions for CSD are in a good agreement with FEM. It is shown that in cases when it depends on CSD only, the predicted shear modulus of laminates is in an excellent agreement with direct FEM calculations.

The phase transition behavior of a high-toughness epoxy–resin system was modeled and simulated as a function of the toughening agent, polyethersulfone (PES), and its content to optimize the resin system. Reliability was ensured through experimental validation. At the maximum PES content compatible with the base epoxy–resin and curing agent contents, the epoxy–resin system exhibited the highest tensile strength and toughness. However, results from preliminary tests performed using the pilot process revealed that an increase in viscosity beyond a certain level due to the addition of PES rendered it unsuitable for application in mass-production processes. The optimal composition of the high-toughness epoxy–resin system suitable for mass production was determined based on the results of the resin paper production using the pilot process. High-toughness carbon fiber-reinforced plastics (CFRPs) were then mass produced, and their characteristics were compared with those of conventionally toughened CFRPs and the pilot products. The results confirmed that compared with the conventionally toughened CFRPs, the mass-produced CFRPs containing the high-toughness resin system showed 246%, 728%, 392% and 480% improvement in compression-after-impact strength, Mode-I interlaminar fracture toughness (ILFT), Mode-II ILFT for crack initiation, and Mode-II ILFT for crack propagation, respectively.
