Industrial paper has two principal directions, called the \u201cCross\u201d and \u201cMachine\u201d Directions (CD\/MD). The deformation characteristics are much more ductile in CD than in MD, but the fracture stress is higher in MD [20]. We tested a number of samples for both directions, with strips of width 30 mm. The weight used for the creep ranges from 380 g to 450 g for CD case and from 450 g to 533 g for MD case.<\/p><\/blockquote>\n<p>I&#8217;ll never look at copy paper the same way again.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The surprisingly rich physics of peeling paper [T]he physics of peeling paper almost exactly mimics the stick-slip movement of tectonic plates, right down to the statistics of the time between \u201cquakes\u201d and the correlations between released energy and aftershock activity. &hellip; <a href=\"http:\/\/blogs.scienceforums.net\/swansont\/archives\/349\">Continue reading <span class=\"meta-nav\">&rarr;<\/span><\/a><\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[39],"tags":[],"class_list":["post-349","post","type-post","status-publish","format-standard","hentry","category-physics"],"_links":{"self":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts\/349","targetHints":{"allow":["GET"]}}],"collection":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/comments?post=349"}],"version-history":[{"count":0,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/posts\/349\/revisions"}],"wp:attachment":[{"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/media?parent=349"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/categories?post=349"},{"taxonomy":"post_tag","embeddable":true,"href":"http:\/\/blogs.scienceforums.net\/swansont\/wp-json\/wp\/v2\/tags?post=349"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
