Hi All,
I have to do a four point flexural test for sandwich
I have to find a suitable Face for my core of the sandwich.
I am to choose one of these three choices:
first selection: 2 layers 0°/0°
second choice: 2 layers 0°/90°
third choice: 2 layers -45°/45°
I am for first choice(0°/0°), because Faces can only be loaded under normal stress!
am I right?
