On augmenting students’ learning in beam structures using numerical simulations

Abstract

Virtual laboratories are seen as an alternative to the delivery of traditional laboratory activities. Additionally, it can be used to supplement or complement traditional teaching practices, especially for engineering topics that are typically assumed by students to be difficult to grasp. In this paper, the use of numerical simulations for a laboratory exercise on a major course in aerospace engineering will be discussed. Moreover, the influence of finite element analysis (FEA) on the learning process of students regarding beam profile and bending performance will be highlighted. SolidWorks program was used for the modeling and structural analysis of beam profiles under predetermined conditions. Numerical model verification and validation were made using established formulae and theories from engineering mechanics. This method was later implemented under the aerospace laboratory course for aerospace engineering students. Fourteen (14) students were asked to report the results of their simulations as well as observations on the structural performance of the beams through a laboratory report. Students' consent to perform content analysis of their reports was secured through Google survey. Applying FEA, students were able to establish connections between beam profile, moment of inertia and bending stiffness, which are often hard to explain in traditional teaching methods. Further, students better appreciate theories associated with beams and their application to aircraft structures. As we navigate a VUCA environment and rapid advancements in computing, numerical simulation programs can supplement or provide alternative avenues where students can learn topics that are conventionally perceived to be challenging.
