This study developed a calculation model and an experimental model of rock breaking of polycrystalline diamond compact (PDC) and diamond impregnated cutter (DIC) hybrid bit to reveal the influence of bit structure and material on tangential force, axial force and wear height. On the basis of the calculation model of the co-rail arrangement of the PDC – DIC hybrid bit and the rock breaking mode, a rock breaking mechanical parameter prediction model and a rock breaking performance test model were established. Rock stress calculation method, rock failure criterion, and mechanical specific energy (MSE) calculation method were used to analyze the rock stress and the relationship between MSE and tangential force, axial force, and wear height during combined rock breaking. The accuracy of the model was verified by experiments. Results show that the specific work of rock breaking of the PDC-DIC hybrid bit is less than that of PDC, and a reverse nonlinear relationship exists between specific work of rock breaking and wear height. The energy required for hybrid bit to break rock is less than that of PDC bit. A positive nonlinear relationship exists between the energy of PDC-DIC hybrid bit and the wear height, whereas the cutting depth and the wear height show a negative nonlinear relationship. The stress distribution of PDC rock breaking is uniform, and the maximum equivalent stress is up to 104 MPa. The stress distribution of rock breaking of the hybrid PDC-DIC is extremely nonuniform, and stress concentration occurs with a minimum equivalent stress of 84 MPa and a maximum stress of 161 MPa, which is beneficial to rock breaking. Rock breaking of PDC-DIC hybrid bit can promote the generation and development of rock cracks, thereby reducing the crushing strength of the rock. The study provides a design method and theoretical basis for designing a new type of PDC-DIC hybrid bit, with certain reference for exploring the rock breaking mechanism of various bits","PeriodicalId":15707,"journal":{"name":"Journal of Engineering Science and Technology Review","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82353662","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}

But, traditional data sharing, along with access control techniques, have been a significant problem in the field of research that includes leakage of privacy information and key misuse. Transferring Electronic Records (ER) on the cloud has allowed data sharing among various health applications. Therefore, two major contributions are created in this study to provide effective access control and private data sharing as well as retrieval within the cloud based on blockchain. In the initial contribution is blockchain-based access control and sharing method effectively resolves the single point of failure within the cloud infrastructure. The Data User (DU) generates an application for registration based on the ID and password and is then forwarded to the Data Owner (DO). The DO data is incorporated into a transactional Blockchain based by encrypted master keys. The DO secures data while the encrypted file is uploaded into the Interplanetary File System (IPFS). In the second piece of work blockchain structure was created to facilitate information sharing as well as retrieval within cloud platforms.","PeriodicalId":15707,"journal":{"name":"Journal of Engineering Science and Technology Review","volume":"160 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89029862","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}

On the basis of theory of Weibull distribution, the material constitutive relationship suitable for the destruction of cement-stabilized macadam materials immersed in water was proposed. Results show that the strength/elastic modulus of cement-stabilized macadam decreases with the increase in immersion time in water, indicating that water has a weakening effect on cement-stabilized macadam. Linear/nonlinear phases appear in the stress-strain curve. The influence of shape parameters on nonpore compression stage is greater than that on pore compression stage. The damage variable remains constant in the early stage. The stress-strain curve of the damage model is in good agreement with that of the test data. The conclusions obtained in this study provide a significant reference for cement-stabilized macadam engineering.","PeriodicalId":15707,"journal":{"name":"Journal of Engineering Science and Technology Review","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78999623","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}
