A very thin rectangular plate (see figure (a)) is subjected to a biaxial plane stress state (σx, σy). The width and height of the plate are b = 7.5 [in] and h = 2.5 [in], respectively. The measures show that the strains in the (x, y) directions are εxx = 2.85x10−4 and εyy = −1.90x10−4, respectively. Figure (b) shows a 2D front view of the plate.
