{"id":1498,"count":7,"description":"Metallic materials \u2013 Test method for the determination of the resistance to quasistatic fracture of welds\r\n\r\nISO 15653:2010 specifies methods for determining fracture toughness in terms of K (stress intensity factor), \u03b4 (crack tip opening displacement, CTOD) and J (experimental equivalent of J integral) for welds in metallic materials.\r\n\r\nISO 15653 is complementary to ISO 12135, which covers all aspects of parent metal fracture toughness testing and should be used in conjunction with this document. Describes methods for determining point values \u200b\u200bof fracture toughness. It should not be considered a way to obtain a valid R-curve (crack resistance-extension curve). However, the sample preparation methods described in ISO 15653 could usefully be used when determining R-curves for welds. The methods use precracked fatigue samples that have been notched, after welding, in a specific target area in the weld. Methods are described for evaluating the suitability of a weld for placement of notches within the target area, which is either within the weld metal or within the weld heat affected zone (HAZ), and then, where appropriate, for to assess the effectiveness of Crack fatigue in sampling these areas.","link":"https:\/\/techlabsystems.com\/eng\/iso\/1-2-3\/iso-15653\/","name":"ISO 15653","slug":"iso-15653","taxonomy":"iso","parent":1395,"meta":[],"acf":[],"_links":{"self":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso\/1498","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso"}],"about":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/taxonomies\/iso"}],"up":[{"embeddable":true,"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/iso\/1395"}],"wp:post_type":[{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/product?iso=1498"},{"href":"https:\/\/techlabsystems.com\/eng\/wp-json\/wp\/v2\/normas?iso=1498"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
