Sir. Flexure of a floating ice tongue: comments on Dr G. Holdsworth’s letter

I would like to express appreciation of Dr Holdsworth's letter. May I point out that Robin (1958) also presented some relevant observational data, which possibly remain the only relevant observational material available. The observations indicated that there was rough quantitative agreement between the elastic theory of bending and the position of tension cracks, the amount of surface stretching and the observed bending of the surface near the grounding line. There also appeared to be some non-elastic yielding of the ice to which attention was drawn and Holdsworth's paper contributes some new relevant theory on this point.
