Aircraft Structures Modeling is the application stage of finite element analysis. This is probably the most important part of the stress engineering cycle. The fact is that a majority of the effort related to stress engineering is developing accurate or close to accurate loads, at least in the aerospace industry.
Even today, the tried and tested product development cycles involve modeling of the critical structural load path members to determine the loads required for sizing. If the loads are inaccurate, the sizing will also be inaccurate, thus resulting in wasted engineering hours.
So it is critical to understand proper modeling techniques to capture the stiffness of the systems, constraints and applied loading and resulting component loads. This is what you will learn in the Aircraft Structures Modeling course.
