Anyone have any success modelling honeycomb panels with COSMOS? We are trying to model CF skins with AL cores, but have a large number of questions. Here is what we have so far:
Elastic Modulus (Pa or N/m2) X face material modulus of elasticity compression Y face material modulus of elasticity compression Z ???? - use face material value?
Poissons Ratio X face material poisons ratio Y face material poisons ratio Z ???? - use the same as face material value?
Sheer Modulus XY 30% of facing stress YX 30% of facing stress XZ calculate via the core sheer on the plate
Density
- calculate from specs
Tensile Strength - the strength of the adhesive bonding the skin to core - double the tensile strength of the core material (yikes!)
Compressive Strength - double the compressive strength of the core material (yikes!)
Yield Strength - 5% more than tensile strength (???)
thanks
