Response to: Comments on E. Radi, D. Bigoni and D. Capuani, Effects of pre-stress on crack-tip fields in elastic, incompressible solids [International Journal of Solids and Structures 39 (2002) 3971-3996]

We sincerely thank A.N. Guz for having brought to our attention his large contribution to the topic analyzed by us, of which we were obviously unaware [with the exception mentioned in our footnote (2)].As far as the initial observations made by A.N. Guz are concerned, we specify that our formulation pertains to small deformations superimposed upon arbitrary large, homogeneous initial deformation. The similarity of the localization patterns found by us to real experiments [see for instance Vasko, G.M., Leo,P.H. and Shield T.W., Prediction and observation of crack tip microstructure in shape memory CuAlNi single crystals, J. Mech. Phys. Solids 50 (2002) 1843–1867] points out the physical sense of our results
