Though the experimental fact of grain boundary diffusion (GBD) delay due to precipitation of nanoparticles in GB is well-known, it is usually connected with the idea that fine particles which are formed in GB reduce the section of boundary and diffusive flux. The direction of this investigation is the development the Fisher’s model of GBD taking into account simultaneous chemical interaction of diffusive and matrix atoms in GB. The events of this kind – parallel carrying out two processes with participation of the same atoms – are well-known in heterogeneous kinetics.9 As a typical example of those processes it can be considered the steel nitration process.","PeriodicalId":18241,"journal":{"name":"Material Science & Engineering International Journal","volume":"11 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76988815","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}

Due to high strength and safety requirements, these applications require joining composites either to composites or to metals. Composite joints create highly localized stress concentration around the joints that cause failure in the substrates. The fracture toughness is the critical aspect that influence on the failure of the substrates. In this work, fracture toughness is determined for a center crack developed on the surface of the substrate of the composite joints. In FEM analysis, Stress intensity factor (K) and J integral are used to find out the fracture toughness value. The influence of various parameters such as fiber orientation angle, crack length, applied load and bolt hole diameter on fracture toughness is determined with the use of LEFM in finite element analysis. Stress intensity factor and J integral are validated with the theoretical data available. Geometrical parameters which affect fracture toughness are optimized by using Taguchi analysis and design of experiments. The result shows that the crack length is the most significant parameter which affects the fracture toughness substantially. Elasto plastic region (dog bone shape) near the crack tip is also analyzed in this work.","PeriodicalId":18241,"journal":{"name":"Material Science & Engineering International Journal","volume":"17 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83006089","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}

Engineering applications of shock physics including ballistic and explosive impact, as well as any other sort of high energy collision, are found in a range of industries such as armor and weapons. The extreme temperatures and pressures at which shock physics experiments are able to test can simulate the response of radioactive materials during the detonation of nuclear weapons. It is therefore critically important to these industries to have an understand of the plastic response of materials at high temperatures and strain rates. An understanding of material responses is especially important for applications whereby shear bands are generated under extreme high strain rate conditions, such as in automotive and aerospace structures.1‒4 The foregoing serves as the motivation to investigate the appropriate experimental techniques that test the material responses to these conditions. One of the most common methods of investigating the behavior of materials subjected to a continuous deformation at high strain rates on the order of 105107s-1 is to perform shear plate impact experiments.5‒7 In a general plate impact experiment, a gas gun launches a plate projectile towards a thin, circular specimen sandwiched between two additional plates.8 The flyer plate lies in between the projectile and the specimen, while the anvil plate lies behind the specimen. Often, the flyer plate itself is used as the projectile, making direct contact with the specimen. The projectile is guided by a key running through a keyway within the gas gun barrel, keeping it from rotating. A typical schematic of an experiment is depicted in Figure 1.","PeriodicalId":18241,"journal":{"name":"Material Science & Engineering International Journal","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81020793","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}
