From Bruhn, eq.C5.11:
Rs + RL^2 = 1
is the criteria for combined shear and longitudinal stress. This is from NACA-ARR-3K13 "Critical stress for an infinitely long flat plate with elastically restrained edges under combined shear and direct stress", this is for constraints against rotations on...
I am attempting to model the buckling of a plate subject to the following loading conditions
Uniaxial loading
Biaxial loading
Shear loading
Uniaxial-Shear loading
Biaxial-Shear loading
See attached image (shows Biaxial-Shear Case)...
I was wondering if anyone could tell me for sure if skin buckling is permitted to on stealth or supersonic aircraft?
I assume it is not allowed on a stealth plane because the skin buckling would cause a change in the skin shape which is important to the stealth characteristics of the plane...
Hi everybody,
I am trying to write a small script to determine the total geometric stiffness matrix of a FE model containing only triangular plate elements with bending stiffness similar to the NASTRAN TRIA3 elements. I found several definitions of the geometric stiffness matrix (3x3) of such...
