Improving Mechanical Design Education using Solid Modeling and Finite Element Analysis Modules

Abstract – In mechanical design, engineering students are presented with two main charges. The first of these is to design a component or system for a specified function. The second is to mitigate any mechanical failure during its useful life through analysis and re-design cycles. While engineering curricula tend to focus on analysis in some courses and design in others, it is critical for engineers to see analysis as an integral part of design.. For many engineering students (and graduate engineers) it is difficult to determine the location of highest stress in a part by inspection, especially if the loading is three-dimensional. In an effort to better prepare students for professional practice, improve visualization of stresses in designs, and increase student interest, engineering application software was integrated into the junior-level mechanics sequence. Course modules using solid modeling and finite element analysis software were included via single laboratory sessions and assignments emphasizing visualization and relationships between design and analysis. The modules reinforce the mechanics and design theory of the classroom without extensive finite element theory being presented. Descriptions of the modules and their learning objectives as well as results of student feedback are presented and discussed
