The authors regret errors in the printed version of the manuscript affecting the following: Equation (18) is 
Kplate=Ek1t3b2Ea03LT2Ea0N2
Equation (20) is 
Wplate=12(Fmaxplate)2Kplate12σf2Etb2[ln(b/πe)]212Eχ2a03N6/5
Equation (22) is 
χ~N

These changes to Eqs. (18), (20), and (22) do not affect the interpretation of results.

The authors would like to apologize for any inconvenience caused.
