Problem with adding a new material

Dear,

I try to simulate a composite beam that is excisting out of 2 oak beams (3x20x650mm) with in the middle 3 different steels beams with 3 different widths (1, 2 and 3mm) and the dimension of the steel is (1x20x650 mm).

Becaus this is not possible a calculation is been made to find the youns modules of the composite and only 1 beam needs to be drawn.

E = (E1 * t1 + E2* t2)/( t1+t2) t1 thickness of oak, t2 thickness of steel

E for 1mm of steel 38GPa

E for 2 mm of steel 58.25 GPa.

E for 3 mm of steel 74 GPA.

But when I make this simulation in Creo PTC I only get a deflection of 0.0555 mm instead of 0.52 mm?

Hello Oona,

You have a student version and cannot open it with the pro version.

If you are in a school you should be able to unlock your file.

This is Young's Module.

Kind regards.

Denis.

I don't understand why "this is not possible". Why not just make a composite beam assembly, set the properties of each piece, then run your analysis?

Dear Mr Farley,

I don't have any idea how you make a composite in Creo PTC?

I only have a student license is this the problem?

Kinds regards
