The load combination factor, ?, is based on the Option 1 FAD currently in use in the Central Electricity Generating Board&#039;s (CEGB) report No. R\/H\/R6 (R6) and the API-579-1\/ASME FFS-1 fitness-for-service standard. The ? factors for the Option 2 FAD based on ASME B&amp;PV Code Section VIII, Division 2 material stress-strain curves are developed and tabulated here for a wide range materials used for the construction of pressure vessels. The ? factors based on the Option 1 FAD are recalculated here and compared to current published data. The approach utilizing Option 1 FAD methods is evaluated here with regard to its conservatism and applicability to material models other than the Ramberg-Osgood model. In addition, a sensitivity analysis is performed to estimate ? factor errors due to uncertainty in material property parameters. A critical review of the tabulated data in API-579 is performed and errors are identified along with suggested solutions to correct the data.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Material Specific Load Combination Factors for Option 2 FAD Curves<\/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\/wrc\/\"><b>WRC<\/b><\/a><\/td>\n<td>2014<\/td>\n<td>204<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":697150,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2677],"product_tag":[],"class_list":{"0":"post-697140","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-wrc","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\/697140","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\/697150"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=697140"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=697140"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=697140"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
