Jeffrey Martin ME 351-001 09/12/23 Lab 1: Introduction to FEA Instructions: In SolidWorks, create the solid model of the rectangular beam . Transfer the solid model to SolidWorks Simulation. Apply “Alloy Steel” as the material. Apply the loading and boundary conditions (LCs and BCs) . Mesh and run the analysis. Once the analysis is performed, answer the following questions. 1. Provide a screenshot of the beam in wireframe view (isometric view) in SWS. Ensure that the loading conditions, boundary conditions, and origin are clearly indicated in the screenshot. 2. Provide a screenshot of the full beam (isometric view) showing the results of the Z-stress (stress in the Z orientation, σ zz ) resulting from the FEA.

Determine the Z-stress and Y-displacement (on the tensile side of the beam) down the length of the beam at the following locations using the Probe Tool. An image including the “0” point location on the beam should also be included. Experimental Values Location (mm) σZ (M Pa) UY (mm) 0 3.77e+6 0.00 500 1.500e+6 -1.54e-02 1000 4.543e+04 -4.86e-02
Jeffrey Martin ME 351-001 09/12/23 5. Perform calculations in a computer program of choice (Excel, Matlab, Mathcad, etc.) to generate (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. Include values obtained from both SolidWorks and your calculations in the graphs. Place the graphs below and include a screenshot of the calculations performed. \ 0 500000 1000000 1500000 2000000 2500000 3000000 3500000 4000000 0 200 400 600 800 1000 1200 σZ (MPa) Distance along beam (millimeters) σ Z (MPa) -0.06 -0.05 -0.04 -0.03 -0.02 -0.01 0 0 200 400 600 800 1000 1200 Y displacement Distance Along Beam
