Two types of complex objective function are presented with either identical optimum cone-angles in each pass or variable optimum coneangles being able to differ between the drawing passes. Through this calculation, the results of the complex optimization were characterized and the results are compared with the original operating parameter values.","PeriodicalId":340250,"journal":{"name":"MultiScience - XXXIII. microCAD International Multidisciplinary Scientific Conference","volume":"223 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127632569","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}

In this study, a methodology for a minimum weight optimization for honeycomb core sandwich panels with composite face sheets is presented, which can be primarily used for manufacturing of the walls, floor and roof of containers. The honeycomb sandwich panels consisted of symmetric composite face sheets the face sheets consisted of E-glass / epoxy fiber-reinforced plastic. The lay-up of the fibers of the face sheets was limited to sets of plies having orientation angles of 0 and 90. The new lightweight containers provide considerable savings in weight and thus reduce fuel consumption or increase aircraft turnover compared to conventional containers (see Fig. 1). According to the International Air Transport Association (IATA) calculations, the weight of fuel required to carry 1kg additional weight per hour is 0.04 Kg. The weight of the sandwich structure panels considered is the objective function subject to constraints needed based on the stiffness, face sheets failure, skin wrinkling and core shear. MATHLAB software was used to obtain theoretical results and compare them with numerical and experimental results. The strategies of composite sandwich structures depended on classical lamination theory. The program calculates the ply failures automatically by using the Tsai–Hill failure criterion for every combination of face sheet and core thicknesses.","PeriodicalId":340250,"journal":{"name":"MultiScience - XXXIII. microCAD International Multidisciplinary Scientific Conference","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128445224","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}

It is common to treat the dross at high temperature in a rotary “converter” furnace to recover most of the entrapped metal. The efficiency of this process depends on many factors, and the Mg content of the metallic phase is important. We have examined an extensive industrial data base and carried out experiments with a laboratory scale rotary furnace to compare the tapped metal yields from dross tapes divided in groups by the Mg-concentrations of the “mother alloys” generating them primarily. It has been found that a medium Mg-content in the metallic phase can offer the best yields.","PeriodicalId":340250,"journal":{"name":"MultiScience - XXXIII. microCAD International Multidisciplinary Scientific Conference","volume":"38 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133374820","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}
