Utilizing a split-disk test, the study evaluates both experimental and numerical approaches to examine the impact of FO sensors in glass fiber-reinforced polypropylene composite rings. The split-disk test is employed to measure key mechanical properties such as hoop tensile strength, stiffness and failure strain using strain gauges and 3D Digital Image Correlation (DIC). The research specifically examines two extreme configurations of FO sensor placement: parallel and perpendicular to the reinforced fibers. The objective is to propose sensor integration that minimizes potential negative effects on the material's properties. Both instrumented and non-instrumented samples are analyzed numerically and experimentally. The experimental phase involves detailed mechanical characterization using the split-disk test, while the numerical approach uses a developed UMAT finite element model based on the 3D Puck failure criterion and an element weakening method for progressive failure analysis. The numerical models adopt real microstructural details according to optical microscopic analysis. The study concludes that parallel embedded FO sensors are preferable as they enhance the ultimate strength to failure and avoid creating resin-rich zones near the sensor, thereby improving the overall mechanical performance of the composite rings. The 3D Puck failure criterion combined with the element weakening method provides accurate predictions of fiber failure initiation and growth in the composite rings.</div></div>","PeriodicalId":34525,"journal":{"name":"Composites Part C Open Access","volume":"15 ","pages":"Article 100534"},"PeriodicalIF":5.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143180021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fiber Reinforced Polymers Composite (FRPC) is one type of composite that is increasingly used due to its versatility and ability to improve product quality. However, FRPC materials have a high susceptibility to Low Velocity Impact (LVI) events, which can cause invisible internal damage such as delamination. LVI occurs when FRPC materials experience a sudden impact with a foreign object at a speed of 1–10 m/s, and can be identified through drop weight impact tests. This research addresses Finite Element Analysis (FEA) simulations to evaluate the mechanical properties of materials due to LVI, following the ASTM D7136 drop weight impact test standard. The variations studied include material types, namely Carbon Fiber Reinforced Polymers (CFRP) and Glass Fiber Reinforced Polymers (GFRP), as well as variations in the diameter of the impactor. The results showed that GFRP has more brittle properties than CFRP, which is indicated by the high absorption energy and larger maximum back surface displacement in CFRP. In addition, the damage in GFRP is more significant as CFRP requires a higher initiation force and energy to trigger and propagate the damage. The simulations also show that as the diameter of the impactor increases, the contact force increases, but the impact time is shorter. In contrast, a smaller diameter impactor penetrates the material more easily, with a smaller impact area and lower impact energy after contact occurs.</div></div>","PeriodicalId":34525,"journal":{"name":"Composites Part C Open Access","volume":"15 ","pages":"Article 100541"},"PeriodicalIF":5.3,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142707079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We also find that linear elastic stress fields are more accurately predicted using a long-short term memory neural network rather than a convolutional decoder neural network. We show indirect prediction of characteristic length, via prediction of failure loads and linear elastic stress fields independently, results in more flexible, interpretable and accurate results than direct prediction of characteristic length, given sufficient training data.
