Composite problems

[Pro.kai]

Hey!


I`m doing a final study in school and was locking forward doing som analyses in Pro-E


I compare different combinations of carbonfiber laminates and core panels


The carbonfiber laminates and core have ofcourse different technical data and iwas hoping to find the ideal combination of different laminates and core thickknes and density. to do so i will perform stress and sheer analyses but i don`t know how to use the composite function or if at all is possible to have different material properties in one part..


Thanks

I suppose not, but I can be wrong.

Take in mind that if your whole part(which I assume is made of two materials) has anisotropic conditions, you can not analise it in Pro\Mechanica, while Pro\M does not deal with anisotropic materials

I won`t be using anisotropic conditions. just differnt E-module and density.

 

[Jacoolo]

well all what is left is just discussion

For sure one model with one material will not behave exact as with two materials because there is this different behaviour on the border of materials

I suppose You can choose the E-module for the weaker mateial and count the density to achieve real mass

but, I am sure You already know it, so I would also be intersted to hear if auch func in Pro\e exist for coposit materials

 

[Pro.kai]

For stress analysis the carbon laminate takes up all the loads with the core just working as a stiffener. I want to find the ultimate core with the less thicknes and lowest density for each laminate combination. For the sheer analysisthe core takes up all the load and i won`t use the carbon laminat for those analysis.


I have heard that i should be able to link the to elements together so it will work as one.
