Thus, different sample combinations were created with two different foams, PVC (80 kg m−3) and aluminum (200, 350 kg m−3), which were used as filling materials. The first group of samples consisted of uniform foam-filled aluminum tubes. In contrast, tubes were filled with radially graded foams in the second group, which included a ring PVC foam and a cylindrical aluminum foam in the center. Empty tube absorbed 329 J, while it reached the values of 384, 488, and 606 J by using PVC and low- and high-density aluminum foams, respectively. The specific energy absorption value of the empty tube was obtained as 23.2 J g−1. In comparison, it was 19.3 J g−1 in the high-density aluminum foam-filled sample, although it absorbed the highest energy value. This shows that high-density aluminum foam was inefficient in terms of the crashworthiness of the structure. Finally, the best sample regarding the specific energy absorption and crush force efficiency was obtained in the sample where the PVC foam ring and high-density aluminum tube were used together. This sample had 7 % higher specific energy absorption and 34 % higher crush force efficiency than the empty tube.","PeriodicalId":18231,"journal":{"name":"Materials Testing","volume":"15 6","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139438814","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In additive manufacturing, production can be carried out using thermoplastic and metal materials without requiring an additional process. Among the additive manufacturing technologies, the Fused Filament Fabrication (FFF) method is the most widely used method worldwide due to its affordability and broad application area. FFF is a method in which part formation is achieved by depositing melted materials on each other. In recent years, polymer materials such as polylactic acid (PLA), polyethylene terephthalate glycol (PETG), and acrylonitrile butadiene styrene (ABS) have been frequently used in many industrial areas in the FFF method because they are lightweight, inexpensive, sustainable, and provide sufficient strength for engineering applications. This study conducted tensile, three-point bending, Charpy, and compression tests on PLA, PETG, and ABS materials at angles of 15°–75° and 30°–60°, and the results were compared.","PeriodicalId":18231,"journal":{"name":"Materials Testing","volume":"50 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139379993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This has various advantages compared to previous, user-dependent analyses, in which the same results are analyzed differently by different persons. Even though these differences are only of a certain degree, they can lead to false estimations of underlying material and process parameters as well as to missing comparability. In order to automatize previously user-dependent processes in the analysis of material tests, a modular database management system, called idCarl, has been developed. This system places a module as analysis pipeline between the experimental machine and the database. The database management system can be expanded with diverse modules, enabling the generation of user-independent data, which are fed automatically into the database. To provide an example, a module is applied to the common procedure of tensile testing based on DIN EN ISO 6892 and CWA 15261-2. The module determines automatically Young’s modulus and other parameters derived thereof. The method for determining the measurement uncertainties of the Young’s modulus is improved and compatibility with the “Guide to the expression of uncertainty in measurement” (GUM) is achieved. The existing method in ISO and CWA standards provides in some cases an underestimation of about 112 %.","PeriodicalId":18231,"journal":{"name":"Materials Testing","volume":"47 7","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139380091","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This article uses ANSYS for numerical simulation to study the effect of laser heat input on the deformation of the rotor shaft during laser cladding process. Simulate and analyze the temperature and stress fields inside the rotor shaft using thermal coupling. The results show that by changing the pitch, axial cladding width and laser irradiation duration to change the laser induced total heat input, a more uniform temperature distribution can be generated in the rotor shaft. The increase of temperature distribution uniformity can reduce the deformation of rotor shaft during cladding. Using a cladding equipment, iron based customized alloy powder was coated on the 45 steel rotor shaft for cladding experiments. And the mechanical properties and coaxiality of the rotor shaft after cladding were measured. The results showed that the hardness and wear resistance of the cladding layer were significantly improved compared to the substrate, and the changes in coaxiality of the rotor shaft were consistent with the simulation results, with relatively small errors. It is of great significance for repairing damaged rotor shafts.","PeriodicalId":18231,"journal":{"name":"Materials Testing","volume":"10 10","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139380231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to investigate the effect of core configurations on mechanical performance and deformation behavior of metallic sandwich panels under low-velocity impact loading. For this purpose, metallic sandwich panels having monolithic and sliced core configurations were first produced. Low-velocity impact tests were carried out using varying energy levels (20, 40, 60 J) to examine how the intensity of influence affects the deformation of the sandwich panel. The perforation and deformation behavior on the upper surface plates of sandwich panels were evaluated. Experimental results showed that the core design significantly affects the impact behavior of sandwich panel samples. The sliced core configuration produced approximately 10 % more maximum contact force and absorbed 14 % more impact energy at high-impact energy levels. Additionally, the sliced core configuration delayed core collapse of the core in deformation situations where complete perforation does not occur.","PeriodicalId":18231,"journal":{"name":"Materials Testing","volume":"39 2","pages":""},"PeriodicalIF":2.5,"publicationDate":"2024-01-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139379998","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
