The ultimate tensile strength of<br \/>\nthe materials is less than 850 MN\/sq m and their thicknesses range<br \/>\nfrom 5 to 70 mm. The data have been derived from tests conducted in<br \/>\nlaboratory air at room temperature and mean da\/dN curves are<br \/>\npresented in terms of the stress intensity factor range and the<br \/>\nstress ratio, R. The materials are grouped according to four ranges<br \/>\nof their 0.2 per cent proof stress and where possible the upper<br \/>\nlimit of scatter of the data is also provided. The range of da\/dN<br \/>\ncovered is from 10E-8 m\/cycle down to the threshold at 2x10E-11<br \/>\nm\/cycle. The effects of variations in mean stress, specimen size<br \/>\nand thickness, and material yield strength are discussed. Details<br \/>\nof all the materials and types of test specimen are tabulated and<br \/>\nsummary da\/dN curves that compare the different groups of materials<br \/>\nare given. Curves showing the effect of variations in the value of<br \/>\nR at threshold for the various materials are also presented. Simple<br \/>\nworked examples illustrate how the data may be used in<br \/>\npractice.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Fatigue Threshold Stress Intensity Factors and Slow Crack Propagation Rates in Low and Medium Strength Low Alloy Steel<\/b><\/p>\n<table style=\"width: 100%\" border=\"0\" cellspacing=\"0\" cellpadding=\"0\">\n<tbody>\n<tr>\n<td>Published By<\/td>\n<td>Publication Date<\/td>\n<td>Number of Pages<\/td>\n<\/tr>\n<tr>\n<td><a href=\"https:\/\/pdfstandards.shop\/product-category\/publishers\/esdu\/\"><b>ESDU<\/b><\/a><\/td>\n<td>2013-01<\/td>\n<td>24<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":558339,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-558329","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-esdu","8":"first","9":"instock","10":"sold-individually","11":"shipping-taxable","12":"purchasable","13":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/558329","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media\/558339"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=558329"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=558329"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=558329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
