Taking a cue from their light weight and good strength properties, lot of work has been carried out in the development composite materials using organic and ceramic reinforcements like graphite, TiC, SiC, Al2O3, TiB2, B4C and carbon nanotubes. Further, the current trend is using these reinforcements. The idea behind developing aluminium metal matrix composites is to overcome the drawbacks of unreinforced aluminium alloys and conventional aluminium metal matrix composites in order to improve mechanical, corrosion and tribological properties. In addition to this just adding reinforcement to the matrix material doesn’t contribute to overall properties but understanding of processing techniques used for synthesis of composites have significant influence on these aforementioned properties. Fabrication of composites is usually done by conventional powder metallurgy or stir casting technique. So, in order to have composites with good properties a right combination of reinforcement and processing technique is very much important. In this study, Friction Stir Processing was employed to develop a composite layer on the surface of Aluminium Alloy(AA6082) using SiC particles(120 mesh). The effects of Rotational and Transverse speeds on the Surface Hardness of the Friction stir processed layer is investigated. By this method, it is possible to enhance the surface hardness of the Aluminium alloy to even 3 times of the original value.","PeriodicalId":36710,"journal":{"name":"International Journal of Applied Engineering Research (Netherlands)","volume":"30 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75062624","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}

Flow under sluice gate in variation of open gate (a = 1,2,3,4 cm) and variation of discharge (Q) rise the contraction coefficient (Cc) and discharge coefficient (Cd). Fiberglass prototype model as horizontal channel was used for this experimental research with dimension: length (L) = 9 m, width (B) = 50 cm and using sluice gate installed on it, height (h) = 80 cm, thick (t) = 1 cm, width (b) = 50 cm. Two models of baffle block as cubic using end sill (code K1, 16 running, no sill, s1 = 2 cm; code K2, 16 running, s1 = 2 cm, s2 = 2.7 cm) with different dimension (Bb1 = 0.7 cm, Bb2 = 1.4 cm) installed as three row, specified location 25 cm after sluice gate. During each running test with variation open gate and discharge, the velocity (v) and height of flow (h) were measured then Froude number, contraction coefficient (Cc) and discharge coefficient (Cd) were analyzed. The result showed that cubic baffle block model K2 (used sill 2 cm and 2.7 cm, Fr = 0.09 0.88) gives the better performance modelling of Cc and Cd in term of the initial Froude number with R = 0.9152 (Cc) and R = 0.9053 (Cd). It was concluded that using three rows configuration of cubic baffle block with K2 model (1.4 cm x 1.4 cm x 1.4 cm) gave better model than K1.

This makes the hydraulic fracture more complex to propagate. Stress distribution around a wellbore is investigated in different fluid flowing conditions. The partial coupling strategy is applied to get effective stress from the stress model and fluid flow model. Finite Element Method is used to calculate the total stress distribution and the effective stress with fluid pressure. A numerical model is developed and verified by a commercial software and analytical solution. The developed numerical model is applied to generate the effective stress distribution. Numerical experiments are conducted to find out the factors to the effective stress. The results from current model suggest that it can effectively capture the total stress distribution and effective stress distribution around the wellbore. Model also suggests that fluid pressure has a significant effect on the stress distribution. The results from numerical experiments show that effective stress increases with wellbore radius and rock compressibility, but decreases with the fluid injection rate and rock compressibility. The results of this study can be used to improve the simulation of stress distribution near a wellbore for hydraulic fracturing design.","PeriodicalId":36710,"journal":{"name":"International Journal of Applied Engineering Research (Netherlands)","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72827690","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}

Factors that cause coastal erosion and environmental degradation in coastal areas are due to natural and human activities. Management policies that ignore the degradation of the coastal environment will result in misleading policies. The purpose of this study is to identify the causes of erosion and damage to the environment of Sowan beach which is a coastal tourist attraction in Tuban Regency. Coastal vulnerability assessment was done by using scoring on seven parameters of human activities. Primary data to determine population activities that influence erosion and damage to the coastal environment was done by distributing questionnaires randomly to 100 communities around Sowan Beach. Based on the results of the Sowan beach vulnerability scoring because human activities indicate conditions that are very vulnerable, a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. the results of the vulnerability score of Sowan Beach caused by human activities indicate that conditions are very vulnerable, so a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. The results of the vulnerability score of Sowan beach caused by human activities indicate that conditions are very vulnerable, so a strategy is needed to reduce human activities that are detrimental to Sowan's coastal environment. Based on community perceptions, there are 4 destructive human activities; the absence of coastal protection (30%), the presence of wild sand mining (35%), tourism activities themselves (20%) and capture fisheries activities (15%).","PeriodicalId":36710,"journal":{"name":"International Journal of Applied Engineering Research (Netherlands)","volume":"48 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86965094","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}
