This presentation was made at NAFEMS UK Conference 2018, "Taking Engineering Analysis and Simulation to the Next Level".
The NAFEMS UK Conference 2018 brought together all those involved in analysis and simulation from every corner of industry and academia, giving them an opportunity to advance their knowledge, give their organisations a competitive advantage, and a chance to be part of improving the technology itself.
Recent advancements in the field of numerical analysis enable engineers to solve complex problems using finite element analysis. These advancements aid in the investigation of responses of physical problems to their environment in a way that was not possible in the past. Using these tools, the engineering communities would like to depend more extensively on analytical approaches to investigate the subjects of their studies, where testing was traditionally used for that purpose. There is also a desire to replace certification tests by test-validated FEM. In each case, the reliability of these numerical solutions are a major concern. Certain regulatory requirements allow analytical approaches to be used for compliance purposes as an option to testing. In all cases these regulations require validation of the analysis before the results can be accepted. The current presentation identifies the federal aviation regulations that allow analysis as a means of compliance for the structural problems and provides acceptable means of validation of this analysis. This presentation provides a brief introduction to finite element analysis as an analytical tool with steps and recommendations for building a compliant numerical model. Examples of most recent advancements in the field of numerical methods in the aerospace industry are presented and discussed.
