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([tex]\alpha[/tex])=k-1/k. 2. Relevant equations The simple shear is given by (ytan([tex]\alpha[/tex]),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.
