INTRODUCTION TO FINITE ELEMENT ANALYSIS

Finite Element Analysis

FEA consists of a computer model of a mathematical or design that is stressed and

analyzed for specific results. It is used in new product design and existing product refinement. Acompany is able to verify a proposed design will be able to perform to the client specifications

prior to manufacturing. Modifying an existing product or structure is used to qualify the product.

In case of structure failure FEA is used to help determine the design modifications to melt the

new condition.

There are generally two types of analysis that are used in industry. 2D modeling

and 3D modeling while 2D modeling conserves simplicity and allows the analysis to be run on a

relatively normal computer it tends to yield less accurate results. 3D modeling however produces

more accurate results while scarifying the ability to run on all fastest computer effectively within

each of these modeling schemes the programmer can insert numerous algorithms which may takethe system behave linearly or non-linearly.

FEA Working Principle

FEA uses a complex system of points called nodes which make a grid called a

mesh. This mesh is programmed to contain the material and structural properties which define

how the structure will react to certain loading conditions nodes are assigned at a certain density

throughout the material depending on the anticipated stress levels. Usually have a higher node

density than these which experience little or no stress points of interest may consists of fracture

point of previously tested material. The mesh acts as a spider mesh is that from each node these

extend a mesh element to each adjustment nodes.

Each FEA program may come with an element library or one is constructed

overtime. Some sample elements are

i. Rod elements

ii. Beam elements

iii. Plate, shell, composite elements

iv. Solid element

v. Spring and Mass element

vi. Rigid element

vii. Viscous damping element.

Main steps of FEA Process.

(i).Model Creation.

A detailed model of the component is drawn is 2D or 3D space according to the

requirement. The model can also be made in preprocessor or some different CAD package and

data can be then transferred to make a new model according to the analysis being carried out.

(ii). Applying Mesh.

Mesh generation is a process of dividing the analysis process into finite element

to set better results. The finer the mesh more accurate the results and longer the time taken.

Aim of mesh generation is to create a minimum number of elements is order to

reduce the processing time.


3/37

(iii). Assigning Properties.

Material properties such as density, thermal conductivity coefficient of heat etc

are defined and their effects are analyzed under different operating conditions. Optimization goal

such as addition of material and removal and design modifications are also defined. Areas where

in weight can be reduced are indicated along with design suggestions to minimize the chances ofpart failure.

May FEA programs also equipped with the capability to use multiple materials

within structure such as

i. Isotropic.

ii. Orthotropic.

iii. Anisotropic.

Types of Analysis

(i).Structural Analysis:

Consists of linear and non-linear models. Linear models use simple parameters

and assume that the material is not plastically deformed non linear models consists of stressing

the material part its elastic capabilities.

(ii). Vibration Analysis.

It is used to test the material against random vibrations. Shock and impact each of

these incidents may act upon natural frequency of the incidents may act upon natural frequency

of the material which is turn may cause resonance and subsequent failure.

(iii).Fatigue Analysis.

Fatigue analysis helps designers to predict the life of material or structure by

showing the effects of cyclic loading.

(iv).Heat Transfer analysis.

Heat transfer analysis models the conductivity or thermal fluid dynamic of the

material or structure. This may consists of a steady state or transient transfer.


4/37

Results of finite element analysis

FEA has become a solution to the task of predicting failure due to

unknown stresses by showing problems is a material and allowing designers to see all the

theoretical stresses within. This method of product design and testing is far superior to the

manufacturing costs which would be accurate if each sample was actually built and tested.

and define the parameters associated with it. You can also select which variables you want to

included in the output files in this modules. You apply loads over a step. To apply a sequence ofloads create several steps and define the loads for each of them.

1. Select Create Step from the Step Toolbox.

2. Name the step as you want and select Coupled temp-displacement as the procedure. ClickContinue.

3. The edit step dialog box lets you choose the solution technique, the solver type and definethe time stepping strategy.

4. Under Basic change the Response to Steady-state and click OK.

The Interaction Module allows you to set up interactions (contact, film), constraints,

connectors, fasteners and wire feature between parts. Our problem does not involve any of these

features but it will be a good idea to explore this module on your own at a later time.

Select Module: Load from the toolbar above.

LOAD MODULE:

The Load Module is where you define the loads and boundary conditions for your modelfor a particular step (indicated in the toolbar above). You can even define loads and boundary

conditions as fields like electric potential, acoustic pressure, etc.

1. Select Create Load from the Load Toolbox. Select Surface Traction and click Continue.Select the top face of the cylinder (z=1) (it gets highlighted in red) and click Done.

2. Change the Traction type to General. Click on the Edit tab under Direction in the dialog

box. Enter the starting point of the direction vector as (0, 0, 0) and the end point as (0,0,1). Enter the Magnitude as 2e5 and click OK.

3. Select Create Boundary Condition from the Load Toolbox. Select Symmetry /

Antisymmetry / Encastre and click Continue. Select the bottom face (z=0) of the cylinder

and click Done. Select Pinned (U1=0, U2=0, U3=0) and click OK.

4. Again select Create Boundary Condition from the Load Toolbox. Switch Category to

Other and select Temperature and click Continue. Select the bottom face of the cylinder

and press Done. Enter the magnitude as 273.15 and click OK. Similarly put the top faceat 274.15.

Now that we have defined the loads and the boundary conditions we move on to mesh thegeometry.

Select Module: Mesh from the toolbar above the viewport.

MESH MODULE:

The mesh model controls how you mesh your model the type of element, their size etc.

1. Select Seed Part Instance from the mesh toolbox. Enter the approximate global size as

0.025.

2. Click on Mesh Part Instance and then on Yes to mesh the model.

3. Select Assign Element Type from the mesh toolbox. Under Family select Coupled

Temperature-Displacement and switch Geometric Order to Quadratic. Click OK.

When finished

select Module: Job from the toolbar above.

JOB MODULE:

This module allows you to submit your model for analysis.

1. Select Create Job from the Job Toolbox. Name the job as you like. Select your model andclick Continue.

2. You can add a description to the job, allocate memory, allot multiple processors and

select precision. Use the default values and click OK.

3. Select the Job Manager from the toolbox and click on the Write Input tab.

4. If you are running the job for the first time it is advisable to run Data Check to check the

input file for errors. Click OK to overwrite the job files.

5. Once the data check is completed Submit the job for analysis. Click OK to overwrite the

job files. You can click Monitor to observe the progress of the solution process. You cansee the errors, warnings, data and message file.

6. Once the job is completed click on the Results tab on the job manager. This opens theVisualization Module for post processing.

VISUALIZATION MODULE:

This model allows you to look at your model after deformation. You can also plot values

of stress, displacement, reaction forces, etc. as contours on your model surface or as vectors or

tensors.

1. Select Plot Deformed Shape from the Visualization toolbox.

2. Select Plot Contours on Deformed Shape to plot stress contours on the model surface.

3. You can see the location of the maximum & minimum stresses by selecting Contour

Options>Limits>Show Location.

4. Select Results>Field Output from the main menu. This opens a dialog box that allows

you to select the variable you want to plot in the viewport.

5. Select U (Spatial Displacement at nodes)>Magnitude>OK to plot the displacement

contours on the model.

6. To plot displacement vectors click on Plot Symbols on Deformed Shape on the toolbox.

7. You can now animate this plot by selecting Animate Harmonic.
