The distribution of the in-plane shear stress, \(\tau_{x y \prime}\) along the \(y\) direction at a particular distance \(z\) from the middle surface of a uniaxially loaded laminate is idealized, as shown in Figure 7.46. The interlaminar stress boundary layer region is assumed to extend inward from the free edge at \(y=b\) by a distance " \(a\)," the in-plane shear stress \(\tau_{x y}=\tau_{c}\) in the region \(0 \leq y \leq(b-a)\) is assumed to be the shear stress from the CLT, and the in-plane shear stress in the boundary layer region \((b-a) \leq y \leq b\) is assumed to be of the form

For the same location, determine the distribution of the interlaminar shear stress, \(\tau_{x z}\) along the \(y\)-direction.
