CFRP Laminate with Delamination 3D

Follow

OnScale is capable of modelling full 3D CFRP components. In this example we will simulate a 3D CFRP laminate with a delamination defect. 

Model Description

This simple 3D 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

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_3D.flxinp)
  2. Select Estimate
  3. Select Run
