Structural Mechanics

The Airy stress function, 22x xy yφ αβγ=++ for a thin square panel of size ll× automatically satisfies compatibility. If the panel is subjected to uniform tensile stress, oσ on all four edges, the traction boundary conditions are satisfied by (A) /2 ; 0 ; /2 .ooα σβγ σ== = (B) ;0 ; .ooα σβ γσ= == (C) 0; / 4; 0.oα βσ γ== = (D) 0; / 2; 0.oα βσ γ= ==
