Enhancing Understanding of Mechanics Courses using FEA Active Learning Modules

Abstract Finite Element Analysis has become an important simulation tool in academia and industries. To take full advantage of this incredible engineering tool, FEA has been integrated in lower-level mechanics courses such as statics, mechanics of materials, machine design etc. It should be noted that most mechanical engineering undergraduate programs offer FEA as an upper-level technical elective or required course. Although the integration of FEA in mechanics and/or design courses is an existing concept, the practice is limited to the use of FEA software package such as how to create a CAD model, how to set up a problem, and obtain a simulation. Simulation of stress analysis of 2D truss bridge, 2D beam frame using a simulation software can be mentioned as examples. On the other hand, the class-room instructions of mechanics courses are primarily limited to solving problems from different textbooks. The authors propose that the FEA simulation software can be used effectively to enhance the understanding some of the concepts of lower-level mechanics courses. This paper discusses the introduction of FEA active learning modules on combined loading, beam deflection, and critical buckling in mechanics of materials course, a sophomore-level course, and shaft deflection in Machine Design course, a junior-level course. The learning outcomes were discussed in class for each module. The learning outcomes were assessed using following two different ways: 1) conceptual understanding of the content before and after introducing the FEA module was assessed by the assignment grades, and 2) student response on survey questionnaire obtained towards the end of semester. The focus of the assessment and student survey were to determine how effective the integration of FEA package was to understand the concept of any topic in Mechanics of Materials and Machine Design courses.
