Someday in the near future I will need to start calculating sandwich skins.
As far as I have noticed this isnt an easy task.
When approaching such problems I prefer to understand the basics in a non mathematical fashion and then start studying the real mathematical theory required.
Are the following steps right?
1 Calculate to match the required bending of a single skin
2 Calculate the max Buckling load of that skin
3 If buckling happens first, add sandwich and a second skin.
4 The total laminate now due to the new sandwich exceeds the required bending->> decrease the initial skin.
5 Iterate until bending and buckling of the structure fail simultaneously.
The process should be repeated in 0º +45º and -45º direction.
Is this the general scheme?
For simplification purposes should I always try to fit the biggest cylinder possible at that stage and assume the calculations based on that cylinder?
