Through this method, complicated structures made of aluminum alloy are produced in a single setup with incredibly tight tolerances. The present investigation explores WEDM for AA6061 to optimize different process variables for attaining performance measures in terms of maximum MRR and minimum SR. Taguchi’s L18 OA matrix, S/N ratio, ANOVA and Grey Relational Analysis were employed to optimize SR and MRR. It has been noted from ANOVA that pulse on time and peak current are the most influential aspects for MRR and SR with their contributions of 13.33% and 16.25% respectively. Further, the best possible considered parameters setting has been established by applying GRA for MRR and SR are, pulse on time-50µs, pulse off time-13µs and peak current-4 amp.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41421800","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The cutting parameters were varied as follows; cutting speed: 120–140 m/min, feed rate: 0.15–0.25 mm/tooth, and axial depth of cut: 0.3–0.7 mm. For a sustainable machining approach, the experimental works were carried out under a smooth supply of cryogenic coolant which is a mix of liquid CO2, gas CO2, and compressed air. The experimental results revealed that the range of surface roughness obtained is from 0.114 to 0.197 µm. Along the cutting process, the tool wear patterns such as the abrasion, chipping, and the intermittent build-up-edge near the depth of cut cause the rapid increase of tool wear as well as the roughness of the machined surface with a significant correlation between them. However, the roughness was slowly reduced and became stable with the increase of notch wear. The finding could be used as a prediction reference for monitoring surface roughness and tool wear progress under cryogenic conditions. It also provides foundations for further research on machinability under this sustainable approach.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43879496","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Snap-fit is employed to assemble plastic parts because it is an efficient, cost-effective, and fast joining technique. When it comes to snap-fits, you have two options: separable and inseparable. The term separable refers to the ability of the components to be dismantled successfully without breaking, whereas inseparable refers to the plastic parts being permanently attached. This investigation focuses on cantilever snap-fit since it is frequently used in the automotive, aerospace, and other sectors. Numerous aspects and parameters affect the functioning of snap-fits, notably on the forces of the insertion and retention. The parameters are the feature thickness (Tb), beam length (Lb), beam width (Wb), base radius (Rb), mounting (α) and dismounting angle (β). The forces required to attach and detach the snap-fits are thought to increase as the insertion and retention angles increase. The results can be seen that higher insertion and retention angle contributes to higher insertion and retention forces as portrayed from Set 7 with the value of 1.1052 N and -1.0214 N.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46268669","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The water molecules are ionized and adhered in the interface forming the sturn layer is a diffused layer in which molecules can move with the movement of bulk of molecules. Because of these two characteristics, the boundary layer of water molecules is called the electric double layer. The aim of present study is to explore the impact of two fraction surfaces of electric double layer (EDL) on a thin water lubricating film on an elastohydrodynamic lubrication (EHL) line contact problem with a sinusoidal surface roughness. The governing modified Reynolds and film thickness equations are based on mathematical model of electro-viscosity of asymmetrical electrical double layer is analyzed numerically. The viscosity-pressure relation of water and theoretical evaluation pertaining to the effect of electric double layer on film-thickness and pressure distribution of EHL with water film of line contact problem is discussed in detail. The effect of zeta potential on film thickness and pressure is determined using Newton’s-GMRES method with Daubechies D6 wavelet as a pre-conditioner. The results predict that, EDL has less impact on pressure distribution and significant impact on film thickness. The obtained results are compared with results of Dowson and Higginson which are comparable.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42956792","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Presently, bituminous pavements in Malaysia are constantly subjected to high-speed loading of vehicles as well as increased pavement temperature due to extreme solar heat which causes rutting and fatigue failure issues. In this research, the 60/70 and 80/100 penetration grade bitumen were subjected to both physical and rheological testing. Physical testing was used to determine the softening point, ductility, penetration and penetration index value whereas rheological testing chiefly determined the engineering properties of the bitumen such as complex modulus and phase angle which interprets the stiffness and viscoelastic behavior. Physical testing results indicate that the 60/70 penetration grade bitumen possesses lower penetration value, higher softening point, adequate ductility and higher penetration index value compared to the 80/100 penetration grade bitumen. Besides, rheological results show that the complex modulus and rutting factor of 60/70 bitumen indicates good stiffness towards temperature rise compared to the 80/100 penetration grade bitumen, thus, posing better resistance towards permanent deformation. Additionally, the 60/70 penetration grade bitumen generally possesses better elasticity compared to the 80/100 penetration grade bitumen which is observed through the phase angle determination.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89706372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aims to assess the performance of Murum dam using Incremental Dynamic Analysis (IDA) which subjected was subjected to a set of 6 ground motion records scaled to increasing intensity levels by using ABAQUS. A different scale Peak Ground Acceleration (PGA) of 0.05 g, 0.10 g, 0.15 g, 0.20 g, and 0.30 g were applied in this study. Based on the results, the cracking area increases when the acceleration increases due to the high tensile stress. The maximum displacement value was located at the crest part of the dam. The findings revealed that the concentration of stresses in the dam body, especially heel and neck. The maximum normal stress was found at the heel zone of the dam. The trend of maximum shear stress shows a fluctuated value when the scale PGA increased.

Based on this review, aluminium alloy 4043 (ER4043) is an Al-Si alloy frequently employed as a filler wire because it has superior fluidity and significantly fewer flaws in additively built structures. Next, dwell time and cooling efficiency during the WAAM process significantly affect bead geometry. Besides, a finer microstructure can be obtained with a better cooling rate. However, a coarser microstructure is obtained along with the increased deposition height due to heat accumulation and low solidification rate. Heat input is identified as the main cause of porosity, and CMT with a lower heat input is preferable and outperformed GTAW and GMAW in terms of mechanical properties.","PeriodicalId":16166,"journal":{"name":"Journal of Mechanical Engineering and Sciences","volume":null,"pages":null},"PeriodicalIF":1.1,"publicationDate":"2023-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81646366","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
