The nominal cross-sectional dimensions of this specimen are identical to those given in Test Methods E23 (Fig. 4A) for the standard Charpy test specimen. The crack strength will be sensitive to changes in the plane-strain fracture toughness providing the strength of the specimen is determined primarily by crack propagation and not by plastic instability.<\/p>\n<p><strong>Keywords<\/strong><\/p>\n<p>Charpy impact test; Fatigue; Metals and metallic materials; Tension (tensile) properties\/tests-metallic materials; crack strength of slow bend precracked charpy specimens of high-strength; metallic materials, test,; Cracking-crack growth; crack strength (of slow bend precracked charpy specimens of; high-strength metallic materials), test,; Impact testing-Charpy; non-load-bearing (hollow\/solid) concrete masonry units, spec<\/p>\n<p><strong>ICS Code<\/strong><\/p>\n<p>ICS Number Code 77.040.10 (Mechanical testing of metals)<\/p>\n<p><strong>DOI:<\/strong> 10.1520\/E0812-91R97<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p><b>E812-91(1997) Standard Test Method for Crack Strength of Slow-Bend Precracked Charpy Specimens of High-Strength Metallic Materials (Withdrawn 2005)<\/b><\/p>\n<table class=\"shortdes-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\/astm\/\"><b>ASTM<\/b><\/a><\/td>\n<td>1997<\/td>\n<td>4<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":207345,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[1088,2637],"product_tag":[],"class_list":{"0":"post-207341","1":"product","2":"type-product","3":"status-publish","4":"has-post-thumbnail","6":"product_cat-77-040-10","7":"product_cat-astm","9":"first","10":"instock","11":"sold-individually","12":"shipping-taxable","13":"purchasable","14":"product-type-simple"},"_links":{"self":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product\/207341","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\/207345"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=207341"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=207341"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=207341"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
