Stress Simulation in cylinders

It is important to analyze stresses (radial and hoop stress) acting inside cylinders as a result of internal pressures (eg. say due to the flow of fluids). Making sure that the internal pressure does not result in component failure is an important consideration for any engineers.

SolidWorks does a great job of simulating these environments, allowing designers to run by their model without necessarily going through the tedious activities of fabricating a prototype.

We will do a simple demonstration on how to obtain the radial and hoop stresses acting on cylinders due to internal pressures.

We first begin by creating a part (cylinder) inside SolidWorks.

Create a cylinder with the geometry of your choosing.

From here you can proceed to run your static study. Remember that you need to enable the SolidWorks Simulation add-in before you can run any study.

Create a static study by clicking on the green marker.

In the static study, we need to create a Section View of the part in order to define our fixtures.

Use the right and top plane to create the section.

Apply a roller fixture on the cut surfaces.

Next subject the part to an internal pressure of 200psi acting normally on the inner face of the cylinder.

Next, you can define the material of the part and proceed to run the static study.

From the Von Misses Plot, we are able to define both the radial and hoop stress plots by adding a Stress plot. To do so, right click on the Results folder and select Stress Plot.

Choose Sx to define the Radial Stress and obtain the Radial Stress Plot.

To obtain the Hoop Stress, use Sy to define your Stress Plot.

Choose Sx to define the Radial Stress and obtain the Radial Stress Plot.
To obtain the Hoop Stress, use Sy to define your Stress Plot.

The plot above shows the hoop stress distribution across the cylinder walls.
