Stress calculation using SolidWorks

SolidWorks Simulation is a design analysis system fully integrated with SolidWorks. SolidWorks Simulation provides simulation solutions for linear and nonlinear static, frequency, buckling, thermal, fatigue, pressure vessel, drop test, linear and nonlinear dynamic, and optimization analyses.

We are going to analyze a part, analyzing models in SolidWorks is the final step of designing, after this step you completely know what is the maximum stress that can be applied along with other physical quantities like volume, surface area, heat transfer, fluid flow, and other material depending properties.


Extrude the sketch to create a cylinder, this cylinder will act as our final part to analyze stress application on it.

Set the value of extrusion as 100 mm.


This distance is the height of cylinder.

Next, let’s understand the concept of stress and other physical quantities.


Stress like many more physical quantities is a material depending property, what makes stress different from quantities like volume is that volume does not depend upon material. But stress application effects are material dependent.


So, the first thing to do while analyzing is to define material properties.


In this example we will select the material as ANSI 1020


AISI 1020 has high machinability and low hardenability and low tensile carbon steel with Brinell hardness of 119 – 235 and tensile strength of 410-790 MPa. high strength, high ductility and good weld ability. It is normally used in turned and polished or cold drawn condition.


Mn Manganese 0.30 – 0.60 max
P Phosphorus 0.04 max
S Sulfur 0.050 max


These properties are already defined in the directory of SolidWorks. Which makes it easier for us in selecting the material.


Now that we have selected the material properties let’s start SolidWorks Simulation.

To start Simulating in SolidWorks, click on the box with rainbow on its faces.


TIP: In SolidWorks, the colors VIBGYOR represent different values of physical quantities, like red might represent high stress application on an area.

Next, go to Simulation menu and click on Study.


Image 8


This is the study menu pallet in SolidWorks, select static and click ok.

Below you will see fixtures option, this is the option menu where fixed part of model are selected.

Image 11


Select the circular face of the cylinder, where standard (Fixed geometry) is written.


Ensure that fixed geometry is selected.


Image 12


Go to external load, and select ‘force’. You will see force option, this is the option menu where different loads are applied.


Image 13


Select the opposite face of fixed geometry.


Image 14


Set these values which represent the different forces applied on the part.

Next, go to create mesh plot.

Wait for the progress bar to complete.


Image 17


Then click on study part, wait for it to complete then your part will be shown in different colors which will represent the effect of stress applied.

This represents the resulting stress on the fixed part, which is 1.286 N/mm^2.
