Continuous research is being carried out for improving the crashworthiness of the vehicles with different materials. These materials plays important aspect in energy absorption and impact resistant design of the structure, wherein, presence of these materials highly affects the response of structures subjected to impact loading. In the present study, a non-linear finite element code LS-DYNA® is used for numerical simulation of drop weight impact hammer test. The material chosen for simulated testing is polymeric syntactic foam. In this study, effect of density of foam, foam material model, effect of drop height and effect of tube, filled with foam, on energy absorption of foam is studied. Herein, material model chosen for hammer is bilinear material model and crushable foam as well as piecewise linear plasticity model is used to model the foam. Behaviour of foam is compared in terms of reaction force, displacement time history and force-displacement variation. Energy absorption for each model is computed for different velocities considered in the present study and it is observed that tube plays an important role in enhancing the energy absorption of foam.","PeriodicalId":354536,"journal":{"name":"International Journal of Structural Glass and Advanced Materials Research","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121838924","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 sand impingement results into micro cracks and surface flaws which altered the structure and strength of the exposed glasses thereby lowering their service life. In this regard, attempt was made in this research to investigate the influence of acid frosting technique as a means of surface modification on the microstructure characteristics and mechanical strength of eroded soda-lime-silica glass. Several glass samples measuring 80x60 mm were initially prepared and exposed to sand impingement from a sandblasting machine with an air flow speed of 15m/s and an impact angle of 90°. The sandblasted glass samples (Scontrol) were later immersed in Hydrofluoric Acid (HF) for acid frosting procedure at dipping period of 5, 10, 15 and 20 minutes respectively. Microstructure characteristics were examined using scanning electron microscopy while flexural strength test was conducted to assess the mechanical strength of the sample glasses. The results showed that mechanical strength of the etched-sandblasted samples (S+E series) improve significantly as the dipping period increases compared with sandblasted glasses. In term of microstructure, homogenously distributed micro-cracks and numerous flaws were observed on the eroded glass samples while for the S+E series, the stress riser effect of these micro-cracks are well eliminated which accounts for the strength improvement.","PeriodicalId":354536,"journal":{"name":"International Journal of Structural Glass and Advanced Materials Research","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126390311","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}

We consider specialty thin glass (Corning Eagle XG®) as superstrate of the PV module, while a standard tempered Soda-Lime-Silica Glass (SLG) is considered as bottom support. The reliability calculations for the module were performed based on the stress magnitudes obtained from the FEA computations. The PV solar panel considered in this study are supported by C-chanel rails that run along the longitudinal direction. The optimum values for the C-chanel rail support location and height were determined using FEA driven reliability calculations. A methodology involving back calculation of the limiting stresses from the reliability constraints is briefly discussed, that can save the time consuming FEA iterations and tedious post processing of FEA results thereafter to calculate reliability. Analysis shows that the best rail position is between 17% to 20% of the module width (L) from the edge. The channel located at close to L/5 from the free edges was found to give mechanical reliability of 99%. Rail height greater than or equal to 23.5 mm can be used to achieve 95% reliability for the heavy snow load test. Lower modulus encapsulants such as silicone decrease the stress on top glass Eagle EG (EXG) and increase the stress on SLG (bottom glass) to a bit over the temper stress level. The butyl perimeter seal has a minimal impact on glass stress levels.","PeriodicalId":354536,"journal":{"name":"International Journal of Structural Glass and Advanced Materials Research","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126692036","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}
