CFRP Laminate with Delamination 2D

This is a modelling guide to help you get started simulating Carbon Fiber Reinforced Polymer Composites (CFRP) in OnScale. In this initial example you will be shown how simulate a CFRP laminate with a delamination defect. 

Model Description

This simple 2D model simulates an immersion inspection of a CFRP laminate containing a delamination defect. The model comprises of a CFRP laminate with 24 ply layers and thin inter-ply resin layers. The number of plies is variable and their orientation is read into the model from an external CSV file, allowing for different laminates to be simulated.

Download and Open the Model

Download: CFRP 2D

OnScale Input Files have the file extension *.flxinp. To open the downloaded file:

  1. Open OnScale 
  2. Select Analyst Mode
  3. Select the Menu button in the top left of the application
  4. Select Open

Preview Model


Preview model is used to see the geometry dimensions and material assignment of your model to check your script is correct. To preview a model, select the Preview Model icon in the Home tab of the application ribbon.


Note: Preview model will display data from any grph commands that come before the prcs command. If you have more than one grph command, you can cycle through the graphics by continuously selecting Preview Model. To close the preview, select Stop Preview.

Run Model on Cloud 

To run the model on the cloud, select the Run on Cloud button in the Home tab of the application and follow these steps:

  1. Click select and open the file you wish to run (CFRP_Laminate.flxinp)
  2. Select Estimate
  3. Select 8 CPUs
  4. Select Run

Download Results

  1. From the Home tab, select the Storage icon
  2. Select the Refresh icon to refresh storage
  3. Select the Job Name from the dropdown menu
  4. Select Download > Download All

Choose a directory to download the results to. These results will be stored in the folder: CFRP_Laminate-YYYYMMDD-HHMMSS\1 where YYYYMMDD-HHMMSS is the current date and time.
