Finite Element Analysis (FEA) Essentials
8 modules & 5 case studies
"To provide a solid understanding of the different engineering concepts and challenges involved with applying FEA to solve engineering challenges."
About the course
Learning Finite Element Analysis can be challenging and many learning resources focus solemnly on the theoretical backgrounds or on software use. But very important when applying FEA to solve engineering challenges is to have a good understanding of the concepts and design choices involved.
This course teaches you the different approaches used in FEA and the engineering judgment required to properly design models, analyze problems and interpret results. It will help you to understand basic engineering concepts, develop your engineering judgment and gain essential FEA skills. Topics include stress definitions, model preparation, connection rigidity, boundary conditions discussions, realistic load application, meshing, analysis, and post-processing.
This course does not focus on the use of one particular set of software, rather it discusses FEA considerations generic for all software. Demonstrations and examples are given using Femap with NX Nastran.
The course consists of 8 online modules based on video and text content. You receive 1-year unlimited access to the course and the discussions forum. This allows you to perform modules again when you need to refresh knowledge for your work projects.
