Excerpt: ... mg, I am quite certain that the strain put upon it by expansion would have had for its results simply a local elongation, but there would have been accommodation; whereas rigid material has no accommodation, but must yield when, through local action at any one point, the strain put upon it exceeds its absolute strength. This, therefore, appears to me to furnish a very powerful argument in favour of a material of high ductility, and the fault I would find with all these rules is, that the factor of ductility is not introduced as part of the factor of safety. Now, Sir Joseph Whitworth, who has given much attention to this subject, has laid it down as a rule that the value of a material is composed of the sum of its ultimate strength and of its yielding power under strain. I believe that this is a very excellent rule. Therefore if the factor of safety of 5 is none too much for a material that would break when extended 10 per cent., if it could be made to extend 20 per cent., the factor 5 ought to come down to the factor 4; and you would get with that factor at least as much safety as you would get with the factor 5, and the lower extensibility of the material. This is a question which I hope will be very fully and carefully discussed, and I trust that it will lead to a Rule in which both the Board of Trade and Lloyd's surveyors concur, in order to prevent the recurrence of such incidents as I have given you. In the discussion of the Paper "ON THE USE OF STEEL CASTINGS IN LIEU OF IRON AND STEEL FORGINGS FOR SHIP AND MARINE ENGINE CONSTRUCTION," by Mr. William Parker, Chief Engineer Surveyor of Lloyd's Register of Shipping, Sir William Siemens said he thought the Institute should accord their most hearty thanks to Mr. Parker for his very prac Excerpt Journal...
