Optimise ply orientation for minimum deflection

Recommended Posts

Hello,

 

I have the geometry underneath consisiting out of a lot of surfaces.

What is the best way to optimise for optimal fibre direction and laminate thickness, so that each surface reveals it's own fibre orientation.

 

In my previous model I tried assigning all surfaces into a single set:

But after otimization, it seems all the fibre's are directed into the same orientation.

 

-I need a different orientation and thickness for each surface

 

 

Can you help me with this?

 

Best regards,

 

Joep

Hello,

 

I do have this problem now:

 

After optimization almost every ply has a very small angle of orientation. 

Any idea why this is the case?

In the design variables I have assigned a minimum of -180 degrees and maximum of 180 degrees

 

Could it have something to do with radians? since in other test optimizations it worked with these settings.

 

Best,

 

Joep

As suggested, it is always better to start with thickness optimization with a varied orientation. Please see the image for more information.

 

The predicted orientations may not be practical and any degree in the angle may lead to failure.
