Two different speeds of hole expansion tests were conducted within the quasi-static range, accompanied by a uniaxial tension test with a deformation mode similar to hole expansion for supplementary analysis. Finite element simulation was utilized to analyze the detailed deformation behavior within the material, particularly at the hole edge where cracks occur during hole expansion. The mechanical and fracture properties obtained from the uniaxial tension test were incorporated into the simulation, taking into account the anisotropy of the material to predict the precise location of crack initiation within the hole edge. To account for the strain rate effect on the experimentally determined hole expansion ratio, a ductile fracture model was introduced and its necessity was validated by considering the occurrence of material fracture before and after crack initiation. By utilizing 3D solid elements, considering material anisotropy, and applying the ductile fracture model, the simulation provided reasonable predictions for the hole expansion ratio, which exhibited variation with strain rate.</p></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 17","pages":"18886 - 18899"},"PeriodicalIF":2.0,"publicationDate":"2025-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11665-024-10601-8.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145011736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Through in-depth analysis of the microstructure of the connected sample, the relationship between the microstructure and mechanical properties was established.

An intrinsic feature of FDM parts is their poor surface smoothness, which must be managed to increase the industrial use of FDM. The current study adopts Taguchi's L18 orthogonal array to optimize six different FDM parameters, including layer height, extrusion temperature, bed temperature, print speed, raster angle and part orientation, with an objective of minimizing both surface roughness and printing time. Cuboid-shaped samples with circular hole at center in accordance with ASTM standard D-2240 have been considered as experimental sample prepared from nylon filaments reinforced with 8% aramid composites. The measured values of roughness average (Ra), roughness height (Rz) and printing time (PT) have been analyzed through techniques, such as signal-to-noise ratio method, ANOVA, CRITIC-CoCoSo and regression machine learning algorithms. Through CRITIC-CoCoSo, the optimal parameter level which enhances the appraisal score is 0.22 mm layer thickness, 235 °C extrusion temperature, 100 °C print bed temperature, 40 mm/s print speed, 90° raster angle and upright positioned printing. Adaboost algorithm outperformed other regression algorithms with higher R-sq value of 0.99 representing superior performance and decision tree structure developed through has good correlation with ANOVA outcomes and response Table rankings. ANOVA statistical analysis highlights part orientation and print speed as significant parameter for roughness average with 33.76% and 22.29% contribution, part orientation with significant contribution of 39.69% over roughness height, printing time affected by layer thickness and print speed by 62.34% and 28.16%, respectively. Both part orientation and printing speed are effective over final appraisal score with 43.88% and 18.26%, respectively.

The pervious concrete with high permeability and continuous pores is an ideal candidate for the CC to attain a homogeneous carbonation and high CO₂ sequestration efficiency. The aim of this article is to investigate the effect of CC conditions, including pre-curing time, CC time and pressure, on CO₂ sequestration in pervious concrete. Also, the impact on the concrete compressive strength and alkalinity was evaluated. Besides, the microstructure of CO₂ cured pervious concrete was characterized for revealing the mechanism of CO₂ sequestration. The results show that the CO₂ sequestration, alkalinity, and compressive strength of previous concrete are obviously affected by the above CC parameters. As the pre-curing time increases, the amount of CO₂ sequestration first increases and then decreases. Also, when the CC time and pressure raise, the amount of CO₂ sequestration is increased. CC can greatly improve the early-age compressive strength of pervious concrete and make the cement matrix denser, but excessive carbonation results in a decrease in early-age compressive strength. CC can reduce the early-age alkalinity of concrete to some extent, but the effect of CC on the alkalinity is not obvious in the long curing age.

One effective method for welding these components is argon arc welding, which provides a clean and controlled environment for the welding process. This technique utilizes an inert argon gas to shield the weld from contamination, reducing the risk of defects. Improper welding sequences can lead to welding defects such as residual stress concentration and severe deformation, which significantly impact the performance and service life of the towing bracket legs. Therefore, using argon arc welding can help ensure a high-quality weld, enhancing the overall durability and reliability of the towing bracket system. In this paper, five welding sequence schemes are designed to simulate the ABAQUS simulation of Q235/20# steel heterogeneous steel traction seat legs, and the residual stress, strain, and temperature field in the results are analyzed. The residual stress of the specific path is detected by x-ray diffraction method to ensure the accuracy and reliability of the simulation model. The optimal welding sequence scheme was applied to the experimental welding, and it was found that the simulated melt pool characteristics highly agreed with the actual welding melt pool characteristics. Analysis with a scanning electron microscope indicated that the microstructure of the weld joints in the heterogeneous steel was more compact and consistent than that in the homogeneous steel weld joints. No obvious porosity or crack defects caused by welding were found in either type of steel weld joint, and the composition and chemical elements showed gradient distribution to varying degrees. The microhardness curves of the two types of weld joints showed a consistent trend, with the highest hardness in the weld metal area of the 20# side. Performance tests, including dynamic tests and static lifting tests, showed no visible cracks or fractures in the towing bracket legs and the connector plate deformation within allowable limits. In conclusion, a welding strategy of “short to long, internal to external” was developed. The operation of this strategy is to first weld the shorter welds and the internal parts of the weldment to reduce heat input and control the temperature distribution of the joint, followed by the completion of longer welds and the external parts. The method described above is capable of notably decreasing residual stresses in the joint, which in turn helps to limit distortion during welding and boosts the overall mechanical strength of the joint.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":644,"journal":{"name":"Journal of Materials Engineering and Performance","volume":"34 20","pages":"23211 - 23226"},"PeriodicalIF":2.0,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145284450","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}
