Simulations showed that the effect of crack size distributions on the change in fracture strength with porosity decreases as the pore size to crack size ratio increases. For a pore size to crack size ratio of \u00a0&gt;\u223c4, the average failure initiating crack size decreases with increasing porosity. Two regions were defined to describe the relationship between porosity and fracture strength: Region I for porosity less than 20 vol.% and Region II for porosity greater than 20 vol.%. Simulation results were directly compared to the porous glass experiments from the literature.<\/p>\n<\/div>\n<\/section>\n<p>&nbsp;<\/p>\n<section class=\"article-section align-center\"><\/section>\n","protected":false},"excerpt":{"rendered":"<p class=\"post-excerpt\" class=\"post-excerpt\">\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman &#8220;Sensitivity of fracture strength in porous&hellip;<\/p>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/sensitivity-of-fracture-strength-in-porous-glass\/\">Continue reading<span class=\"screen-reader-text\"> &#8220;\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman &#8220;Sensitivity of fracture strength in porous glass.&#8221;\u00a0International Journal of Applied Glass Science, 8(1):116-123, 2017.&#8221;<\/span>&hellip;<\/a><\/div>\n<div class=\"link-more\"><a href=\"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/sensitivity-of-fracture-strength-in-porous-glass\/\">Continue reading<span class=\"screen-reader-text\"> \"\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman &#8220;Sensitivity of fracture strength in porous glass.&#8221;\u00a0International Journal of Applied Glass Science, 8(1):116-123, 2017.\"<\/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-8x","jetpack_likes_enabled":true,"jetpack-related-posts":[{"id":498,"url":"https:\/\/engineering.purdue.edu\/ComputationalMaterials\/index.php\/2017\/11\/04\/failure-variability-in-porous-glasses-stress-interactions-crack-orientation-and-crack-size-distributions\/","url_meta":{"origin":529,"position":0},"title":"\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.","date":"11\/04\/2017","format":false,"excerpt":"\u00d6 Kele\u1e63, RE Garc\u00eda, KJ Bowman\u00a0\"Failure Variability in Porous Glasses: Stress Interactions, Crack Orientation, and Crack Size Distributions.\"\u00a0Journal of the American Ceramic Society, 97(12):3967-3972, 2014.
