I was working on the problem set for and on question 16 and 17 refers to a paper by Charalmbides, Lund, Evans and McMeeking entitled 

"A Test Specimen for Determining the Fracture Resistance of Bimaterial Interfaces." (1989)

I was wondering if anyone has a pdf version of this paper that they can post since I have not been able to access it on google scholar at Harvard and I am currently on spring break away from the libraries.
