ME 350
Fall 2018
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.
1. Provide a screenshot of the beam in SWS. Ensure that the LC’s and BC’s are clearly indicated in
the screenshot.
2. Provide a screenshot of the full beam showing the results of the Z-stress (stress in the Z
orientation, σzz for Amaro’s section) resulting from the FEA.
3. Provide a screenshot of the full beam showing the results of the Y-displacement resulting from
the FEA.
4. Determine the Z-stress and Y-displacement at the following locations (double click in table to
open in Excel):
Location (mm) σZ (Mpa) δY (mm)
0
500
1000
5. 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.
6. 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.
7. Provide the % difference between the stress and displacement results as determined by SWS
and your computer “hand” calc’s.
Location (mm) σZ- % difference

Labs
All Labs are to be submitted via blackboard as
a single .pdf. There will be no exceptions to
this. All labs are due 1 week after they are
assigned.
Make sure that each deliverable has a header
with your name and lab section clearly
indicated
The lab project will be delivered to Amaro’s
office in hard copy on or before the due date
listed on the schedule
CAE and FEA
• Computer aided engineering (CAE) is the use
of computer/computational techniques for
engineering analysis and design.
• ME 350 LAB teaches the use of CAE for
analyzing displacements and stresses in
objects and assemblies of objects.
• Finite element analysis (FEA) is a method of
numerical analysis
FEA
• Powerful engineering analysis tool used for
solving many problems ranging from simple to
very complex.
• FEA can be used for stress analysis, heat transfer,
electromagnetism, fluid flow, and other
applications.
• One of many methods but used widely because
of its numerical efficiency and versatility.
• Usually implemented in commercial software
(e.g. SolidWorks Simulation, ANSYS, Abaqus,
etc.)
FEA
From perspective of FEA methodology the analysis
involves the following steps:
• Building the mathematical model;
• Building the finite element model by discretizing
the mathematical model;
• Solving the finite element model;
• Analyzing the results.
Example FEA Models
Basic Steps in FEA
1. CAD – geometrical modeling of a system or structure
in SolidWorks (SW).
2. FEA - Configuring and running a study in SolidWorks
Simulation (SWS).
3. Calculations using engineering science and mechanics
principles from statics, mechanics, etc. with
computational math tools to verify that the study was
configured correctly and to understand the results.
Requires knowledge of STATICS and MECHANICS OF
MATERIALS.
