Hi guys !
I'm working on Honeycomb materials and I'm going to use it in a sandwich beam. I derive equations and I'm sure about it ! in this equation, I have a shear modulus of core ( means Honeycomb ),G, which I don't know what it is !
I mean in this equation G is G13 or G23 ?!
I also found a book and it was written about honeycomb mechanical properties ! at that book, I formed the S matrix for honeycom, and surprisingly, that matrix isn't symmetric !! what's wrong with it ?!
Please help me !! I really get confused !!...
