If, however, the contact<br \/>\ndimensions are already known from a separate analysis these can be<br \/>\ninput directly into the program.<\/p>\n<p>The program locates the critical stress points with respect to<br \/>\nthree criteria which consider yield failure, brittle failure and<br \/>\nfatigue failure. The program can also produce stress distribution<br \/>\ntables suitable for plotting. The stress distributions can be<br \/>\nconstrained to a cross-section through the contact region or to a<br \/>\nline. Stress distributions around the perimeter of the contact area<br \/>\ncan also be produced.<\/p>\n<p>The program implements the calculation methods of ESDU 78035<br \/>\nentitled &#034;Contact phenomena. I: stresses, deflections and contact<br \/>\ndimensions for normally-loaded unlubricated elastic components&#034;,<br \/>\nESDU 84017 entitled &#034;Contact phenomena. II: stress fields and<br \/>\nfailure criteria in concentrated elastic contacts under combined<br \/>\nnormal and tangential loading&#034; and ESDU 85007 entitled &#034;Contact<br \/>\nphenomena. III: calculation of individual stress components in<br \/>\nconcentrated elastic contacts under combined normal and tangential<br \/>\nloading&#034;. The usual limitations and assumptions of Hertzian theory<br \/>\napply. In particular, the contacting surfaces are assumed to be<br \/>\ntopographically smooth and unlubricated but the results can be<br \/>\napplied with sufficient accuracy to the majority of practical<br \/>\nelastohydrodynamically lubricated contacts. In order to use the<br \/>\nprogram effectively, ESDU 78035, ESDU 84017 and ESDU 85007 must be<br \/>\nreferred to for the theoretical limitations of the method and for<br \/>\ndiscussion of practical considerations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Dimensions, Deflections and Stresses for Hertzian Contacts Under Combined Normal and Tangential Loading (Guide to Use of Computer Program A9434)<\/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>2010-05<\/td>\n<td>NA<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":0,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-559270","1":"product","2":"type-product","3":"status-publish","5":"product_cat-esdu","7":"first","8":"instock","9":"sold-individually","10":"shipping-taxable","11":"purchasable","12":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/559270","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:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=559270"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=559270"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=559270"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
