Davids stuff Flashcards
how to determine most likely failure mode in Tsai Hill Criterion
which of 4 components of equation is greatest
What is R in intercell buckling formula
radius of one cell - like in square and heptagonal arrangements things
Failure methods for sandwich panel in bending
- Maximum deflection
- Face skin failure
- Core shear failure
- Intracell Buckling
- Skin Wrinkling
Failure methods for sandwich panel in compression
- Face skin failure
- General Buckling
- Shear Crimping
- Intracell Buckling
- Skin Wrinkling
formula for safety factor
Max stress / experienced stress
In bending, formula for facing skin failure stress
SEE SHEET
Bending moment formul for uniformly distrubuted load
bending moment formula for simply supported
In bending, formula for core shear failure stress
what is F in bending, formula for core shear failure stress
P/2
In compression, formula for skin failure stress
what do divide N (intracell buckling) by to find force for bending
t
what do divide N (intracell buckling) by to find force for bending- CHECK THIS ONE, THINK THIS MIGHT BE FOR COMMPRESSION
width b, and then divide by 2 to find per skin
2 double angle formula
