Using matlab plot the coordiantes x and y in the horizontal place, and the stresses in the vertical direction of the stress fields given below.

The stresses fields near a crack tip of a linear elastic isotropic material for mode I loading are given by: 30 sin sin cos A/2Tr e) 30 I sin sin COS 20) CoS sin cos xy For K 300 ksivin plot the stresses (each in a separate figure) in the domain 0 s 0 s 90 and 0.02 s r s 0.2 in. Plot the coordinates x and y in the horizontal plane, and the stresses in the vertical direction. Use one figure with three subplots. Label the axis, show grids, provide titles, add colorbar to each subplot
