5 Two-Dimensional Problems in Cartesian Co-ordinate System
Fig. 5.4 Variation of stresses
∴ At y = −h, σ x = −d 3 h
and
At y = +h, σ x = +d 3 h
The variation of σ x with y is linear as shown in Fig. 5.4.
Similarly, if all the coefficients except b 3 are zero, then we get
σ x = 0
σ y = b 3 y
τ xy = −b 3 x
The stresses represented by the above stress field will vary as shown in Fig. 5.5.
