A rectangular beam 2a length and 2b width is loaded by a uniform compressive normal traction (P) as shown: Determine the stresses, strains, and displacement considering the plane stress case. Hint: Decompose the problem into two problems as shown: pa Oy--p/2 Oy-p/2 pa Oyy--p/2 Oyy--p/2 The Airy functions are: a. = CXY+CY + 4XY + C6Xy + 18Y5 b. = CX The overall stress function of the complete problem is the sum of that for decomposed ones.
