Hoop stress prediction

Dear All,

 

Attached is the image of model setup for Radioss.

1. pressing plate

2.outer ring of bearing

3. inner ring of bearing

4. housing

5. cage

6. roller

Aim id to find hoop stresses on housing inner surface.

process is pressing the bearing in to housing and then applying radial load to inner ring.

I solved it with correct physics behavior. but having difficulty to find hoops stress on the housing.

Also, want to save time for the analysis. Will implicit analysis helps to save time?

Hi @Ganesh Munge

You will have to resolve it into Cylinderical system to get hoop stress.

Is there any stress conversion matrix for cylindrical to Cartesian coordinate system???

Is there any stress conversion matrix for cylindrical to Cartesian coordinate system???

 

@Ganesh Munge I didnt get what u r specifically asking for? But i can tell you a simple method to prepare a cylindrical coordinate in deck and then resolve the stress with reference to cylindrical coordinate in hyperview.

Hi @Ganesh Munge

Hoop stress depends on the direction of the cylindrical coordinate system.

To view these stress results in HV, please follow the below steps:

1. Define a Cylindrical Coordinate System in the model and assign the same using the Set Analysis option under Assign radio button in Systems panel.

2. Run the analysis and import the result file in HV.

3. From the definition of Hoop Stress it the Stress acting in the ' theta' direction. So select the Result Type as Stress and Values as 'Y' direction.

Dear @Prakash Pagadala

Should I need to impose my constraints and loading in same co-ordinate system?? or should i keep same?
