1. The problem statement, all variables and given/known data

Hello:

The question is this: To show that a simple shear is equivalent to a pure shear if tan($$\alpha$$)=k-1/k.

2. Relevant equations

The simple shear is given by (ytan($$\alpha$$),0) and the pure shear is (x(k-1), y(1/k-1))

3. The attempt at a solution

I thought that the solution may come up by calculating the strain tensor for each shear. However, they are quite different.

I think that it has something to do with a rotation of the simple shear, but I do not know if it is correct.

Bye.
