Question

1. In the plane-strain compression of a slab between two rough (frictional stress is equal to the shear yield stress, $k$) parallel plates, show that the average compression pressure $p$ is expressed by $\frac{p}{2k} = (n - \frac{1}{2})a + \frac{n + \frac{1}{2}}{4n - 1}a$ where $a = \frac{T}{W}$, for the velocity field given in the following figure.

1. In the plane-strain compression of a slab between two rough (frictional stress
is equal to the shear yield stress, k) parallel plates, show that the average
compression pressure p is expressed by
(p)/(2k) = (n - (1)/(2))a + (n + (1)/(2))/(4n - 1)a
where a = (T)/(W), for the velocity field given in the following figure.
