In this study, the embankment was modeled with three types of geometries and installed on one type of subsoil. The cross-section of all three models has equal dimensions, and it selected from that was reported in the literature, and the length of 24, 48, and 72 m were designed for the embankment-subsoil model. The single type soil was used for modeling embankment and subsoil. The seismic load was applied to the model for assessment nonlinear displacement and vibration mechanism of the embankment-subsoil model. To assess the developed nonlinear displacement, statistical model was applied on the results of the numerical simulation. The results of the statistical model reveal the R2 and root-mean-square error (RMSE) support selection suitable for the geometry of the embankment-subsoil. On the other hand, displacement mechanism associates with the vibration mechanism of the model. With attention to geomorphology of a territory that governs embankment-subsoil model geometry, the appropriate recognition of the impact of model geometry on differential displacement of the embankment-subsoil leads to design an embankment with higher seismic resistance.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"3 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-10-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/mdp2.209","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"112646051","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrospinning has been evolved as the most widely used technique in the recent century. It has been employed in various biomedical applications such as tissue-engineered vascular grafts. This can develop fibrous scaffolds that mimic the structure of extracellular matrix of native blood vessels, suitable for the promotion of cell adhesion, proliferation, and cell growth. There is a growing demand for tissue-engineered vascular grafts for the replacement of damaged or defected blood vessels in cardiovascular diseases. The purpose of this review is to summarize recent developments related to electrospun vascular grafts with different synthetic and natural polymers and electrospinning parameters that affect the final properties of vascular grafts. The main focus of this review is also to describe the previously used materials for electrospun vascular grafts and their applications with respect to small and large diameter vascular grafts.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"3 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/mdp2.203","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"103284349","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this article, coupons with embedded FOBG fiber were tested under alternating bending spectrum and for different peak loads ranging from 30% and up to 60% of ultimate tensile strength at their bottom surface. The differences between the strain measurements of the surface-attached strain gauge and the embedded sensor were almost 2.4% and approximately the same for all the applied peak loads. Application of 65,000 fatigue cycles on several coupons was assessed to simulate the fatigue-loading of the aircraft structures over their life span. The fatigued-coupons were tested afterwards at the same alternate bending-loading spectrum, and their strain measurements were compared against the respective loading spectrum without prior fatigue. The strain measurement differences at peak loads was of the order of 3.0% for the small-applied loads and exceeded 7.0% for the high-applied loads. Fatigue damage after 65,000 cycles was not essentially accumulated in the sensing area of the FOBG sensor, and therefore, its current exploitation in real aircraft structures, for example, a 2-m-long Ω-stringer from carbon preimpregnated fibers from an Aerospace Industry with monitoring capabilities, is proved.","PeriodicalId":100886,"journal":{"name":"Material Design & Processing Communications","volume":"3 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1002/mdp2.204","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"108164768","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The nanofibers that are prepared from renewable materials and their blends can integrate the properties of both nanofibers and renewable polymers. Development of scaffolds that mimic the construction of tissues at nanoscale is a great challenge for tissue engineering. Electrospinning is the most promising technique for nanofibers formation. Nanofibers provide a platform for cell adhesion, proliferation, and differentiation. Therefore, nanofibers from sustainable materials have been used in tissue engineering and biomedical fields.
