Transitioning students to finite element analysis and improving learning in basic courses

Much engineering practice today involves computer aided engineering tools. While the associated underlying theory is often beyond the abilities of many undergraduates, we still must prepare students who will be expected to use such tools in the workplace after graduation. At the same time, computer-based tools may also be used to improve learning in even the most basic subjects. For example, a significant aid in learning mechanics of materials is visualizing the basic patterns of deformations. Using readily deformable objects in class, such as foam bars, is one aid to visualization. This paper describes a very simple Web-based finite element program, which can serve two purposes. First, it acquaints students with the basic steps in carrying out a finite element analysis. Second, this program makes a wide range of deformation patterns available for visual inspection, and thereby can facilitate an increased understanding of some of the variables of importance in mechanics of materials.
