Lab 1

In SW, create the solid model of the rectangular beam on Slide 15.

Transfer the solid model to SWS. Apply the loading and Boundary conditions (LCs and BCs) indicated on slide 15. Apply “Alloy Steel” as the material. Mesh and run the analysis (Thompson will walk through these steps). Once the analysis is performed, answer the following questions.

- Provide a screenshot of the beam in SWS. Ensure that the LC’s and BC’s are clearly indicated in the screenshot.

- Provide a screenshot of the full beam showing the results of the Z-stress (stress in the Z orientation, σ
_{zz}for Amaro’s section) resulting from the FEA.

- Provide a screenshot of the full beam showing the results of the Y-displacement resulting from the FEA.

- Determine the Z-stress and Y-displacement at the following locations (double click in table to open in Excel):

- Perform calculation in a computer program of choice (matlab, Mathcad, excel, etc.) to determine (a) the normal stress (Z-stress as indicated in the slides) as a function of distance along the beam, and (b) the Y-displacement as a function of distance along the beam. See slides 14-23 for example work. Place a screenshot of the computer document below.

- From your computer work (NOT SWS) create (a) a plot of the Z-stress as a function of distance along the beam, and (b) a plot of the Y-displacement as a function of distance along the beam (see slides 22-23). Place the plots below.

- Provide the % difference between the stress and displacement results as determined by SWS and your computer “hand” calc’s.
