This course introduces the design via computers. The finite element method based, computer-Aided Engineering (CAE) software, ANSYS, is introduced. Students are required to run a series of examples to understand the finite element modeling technique, including preprocessing, solution and post-processing, and trained to have "hand-on" experience in going from the theoretical principles to a numerical solution tool. The emphasis is on the design techniques to varieties of engineering structures, including frames, beams, planar machine elements and joints. Structural vibration and thermal stress design analysis as well as optimization will also be introduced.
