The input is<br \/>\nstructured to treat fibre-reinforced laminated plates particularly<br \/>\nconveniently, but will also deal with isotropic materials. The<br \/>\neffects of a uniformly distributed in-plane biaxial loading can be<br \/>\nincluded but, if compressive, should not exceed 30 per cent of the<br \/>\nbuckling load. In-plane shear is neglected, as are shear<br \/>\ndeformation and rotary inertia, and the method relies on small<br \/>\ndeflection, linear plate theory. The program is restricted to<br \/>\nplates in which the shear coupling terms in the stiffness matrix<br \/>\nare zero. The program has been used to illustrate graphically for a<br \/>\ntypical laminated plate the effects of varying curvature and of<br \/>\nvarying the in-plane loading. The input format is explained in<br \/>\ndetail, and a worked example illustrates it and the format of the<br \/>\noutput.\n\t<\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>Natural Frequencies of Singly-Curved Laminated Plates with Simply-Supported Edges<\/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>2011-08<\/td>\n<td>24<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n","protected":false},"featured_media":558889,"template":"","meta":{"rank_math_lock_modified_date":false,"ep_exclude_from_search":false},"product_cat":[2675],"product_tag":[],"class_list":{"0":"post-558879","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\/558879","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\/558889"}],"wp:attachment":[{"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/media?parent=558879"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_cat?post=558879"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/pdfstandards.shop\/wp-json\/wp\/v2\/product_tag?post=558879"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
