The ultimate tensile strength of the materials is less<br \/>\nthan 850 MN\/sq m and their thicknesses range from 5 to 76 mm. The<br \/>\ndata have been derived from tests conducted in laboratory air at<br \/>\nroom temperature and mean da\/d<i>N<\/i> curves are presented in<br \/>\nterms of the stress intensity factor range and the 0.2 per cent<br \/>\nproof stress of the material. Curves are drawn either side of the<br \/>\nmean curve that indicate limits of scatter of 90 per cent of the<br \/>\ndata. The range of da\/d<i>N<\/i> covered is from 10E-5 m\/cycle to<br \/>\n10E-9 m\/cycle. The effects of variations in mean stress, specimen<br \/>\nsize and thickness, and material yield strength are discussed.<br \/>\nDetails of all the materials and types of test specimen are<br \/>\ntabulated and summary da\/d<i>N<\/i> curves that compare the<br \/>\ndifferent groups of materials are given.
