In contrast to earlier studies, here, simulations embody flaw size distributions in addition to pore\u2013pore stress interactions and crack orientation along pore surfaces. Fracture strength of porous glass shows a steep decrease up to 20% porosity and then levels off due to interacting pores. Weibull modulus varies because of the decreased probability of interactions in microstructures containing less than 2% porosity or the smallest pore diameter =48\u00a0\u00a0micrometers. Weibull modulus strongly depends on crack size distributions for porosity less than 2% and pore\u2013pore stress interactions for porosity greater than 5%.<\/p>\n","protected":false},"excerpt":{"rendered":"<p class=\"post-excerpt\" class=\"post-excerpt\">\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman\u00a0&#8220;Failure Variability in Porous Glasses: Stress Interactions,&hellip;<\/p>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/failure-variability-in-porous-glasses-stress-interactions-crack-orientation-and-crack-size-distributions\/\">Continue reading<span class=\"screen-reader-text\"> &#8220;\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman\u00a0&#8220;Failure Variability in Porous Glasses: Stress Interactions, Crack Orientation, and Crack Size Distributions.&#8221;\u00a0Journal of the American Ceramic Society, 97(12):3967-3972, 2014.&#8221;<\/span>&hellip;<\/a><\/div>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/failure-variability-in-porous-glasses-stress-interactions-crack-orientation-and-crack-size-distributions\/\">Continue reading<span class=\"screen-reader-text\"> \"\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman\u00a0&#8220;Failure Variability in Porous Glasses: Stress Interactions, Crack Orientation, and Crack Size Distributions.&#8221;\u00a0Journal of the American Ceramic Society, 97(12):3967-3972, 2014.\"<\/span>&hellip;<\/a><\/div>","protected":false},"author":1,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"advanced_seo_description":"","jetpack_publicize_message":"","jetpack_is_tweetstorm":false,"jetpack_publicize_feature_enabled":true},"categories":[45],"tags":[74,55,14,15],"jetpack_publicize_connections":[],"jetpack_featured_media_url":"","jetpack_sharing_enabled":true,"jetpack_shortlink":"https:\/\/wp.me\/peeeSR-82","jetpack_likes_enabled":true,"jetpack-related-posts":[{"id":490,"url":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/o-keles-re-garcia-kj-bowmanpore-crack-orientation-effects-on-fracture-behavior-of-brittle-porous-materials-international-journal-of-fracture-1872293-299-2014\/","url_meta":{"origin":498,"position":0},"title":"\u00d6 Kele\u015f, RE Garc\u00eda, KJ Bowman&#8221;Pore\u2013crack orientation effects on fracture behavior of brittle porous materials.&#8221;\u00a0International Journal of Fracture, 187(2):293-299, 2014.","date":"11\/04\/2017","format":false,"excerpt":"\u00d6 Kele\u015f, RE Garc\u00eda, KJ Bowman\"Pore\u2013crack orientation effects on fracture behavior of brittle porous materials.\"\u00a0International Journal of Fracture, 187(2):293-299, 2014.
