They are universal approximators and can, in principle, be used to learn any type of model. Their use would be of a great benefit as they can be intended to automate major tasks within an engineering project (such as system dimensioning, certification, and criteria verification). However, it is not yet customary to use these technics for lack of competitiveness against forward engineering calculations. One major issue is the robustness and the difficulty to ensure high precisions for deterministic predictions. In this work, we investigate the ability of neural networks to be used to approximate engineering models and their performance in terms of precision and accuracy per target relative error. Increasing accuracy requires understanding how these models work in a deeper way. Applications on use-cases of mechanical structures are used to understand the behaviour of neural networks for this type of problems and illustrate the encountered constraints.","PeriodicalId":143311,"journal":{"name":"Proceedings of the Fourteenth International Conference on Computational Structures Technology","volume":"12 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":"128521896","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}

The incremental equilibrium equations for a straight thin-walled beam element are derived within the framework of updated Lagrangian formulation and the nonlinear displacement field of cross-sections, which accounts for the restrained warping and the large rotations effects. Shear deformation effects are accounted for the composite cross-section considering bending-bending and bending-warping torsion coupling effects. Cross-section properties are calculated based on the reference modulus, with ability to model different material configurations. A numerical algorithm for calculation of the geometric properties of composite cross-section is developed. Various material configurations are considered. Several benchmark examples are demonstrated for verification purposes. The obtained results indicate that the proposed model can be classified as shear locking free one.","PeriodicalId":143311,"journal":{"name":"Proceedings of the Fourteenth International Conference on Computational Structures Technology","volume":"18 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":"125773288","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}

For this purpose, intelligent artificial neural network (ANN) models were used and compared. A database was build based on and mix composition, curing time and curing method. The model developed to predict the abrasion resistance of the cementitious composites containing granite powder and fly ash was shown to be accurate. This method can be used especially for designing cement mortars with granite powder and fly ash additives replacing cement in the range of 0% to 30% of its weight. These mortars can be used for floors in industrial buildings.","PeriodicalId":143311,"journal":{"name":"Proceedings of the Fourteenth International Conference on Computational Structures Technology","volume":"49 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":"131986112","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}
