Composite results difference

Altair Forum User

Hi,

I'm wondering if there's a difference in the global results of modeling for example a composite T junction with sublaminates or without sublaminates (in this case there will be some overlapping at the junctions). I understand that the one with sublaminates represents the real piece better, but on a complex model it is more time consuming to model every junction. Is it acceptable to create a complex model without these sublaminates?

 

To clarify:

The one with sublaminates:
<?xml version="1.0" encoding="UTF-8"?>

 

The one without sublaminates:


Thanks in advance!

Hi s3b1k3,

 

It is always recommended to model with sub-laminates since there will be no intersections between laminates as shown in fig 2.

you can try this with some simple model. Compare the results with and without sub-laminates

 

Thank you
