Equivalent Plate Vs Layup

Kristina Sornikova · Nov 18, 2016

Dear All,

I model simple plate bending sandwich panel two types.

One type laminate, one with equivalent plate using method here:

https://femci.gsfc.nasa.gov/hcplate/honeycomb_pshell.html

But I find equivalent plate has more deflection and stress than laminate method. What reason is it?

I thank you for help.
Kristina Sornikova.

Need a lot more detail:
- what FEM code? element type?
- how many elements?
- what is the specific loading?
- what are the boundary conditions
- what is the panel layup? and what are the layer material properties?
- what are the property/material cards for each model?
