Basically, I have a square specimen (dimensions 2000&#215;2000 micrometer) with a hole (d = 120 micro) in the center. There is a crack (a=10 micro) located on the right of the hole. The material is glass ceramic, E = 91 GPA.&nbsp;<\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/a3824d5d-7661-4ec8-b897-a99a0137bbd8\/aef6b923-6160-4a07-9b61-a99a013aad79_geometry.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/a3824d5d-7661-4ec8-b897-a99a0137bbd8\/beb4bc25-a804-4e8c-8103-a99a013a9d86_crack.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p><img decoding=\"async\" src=\"https:\/\/us.v-cdn.net\/6032193\/uploads\/attachments\/a3824d5d-7661-4ec8-b897-a99a0137bbd8\/c8405942-2a95-42c5-a03a-a99a013af57d_2018-11-16.jpg?width=690&amp;upscale=false\" alt=\"\"><\/p>\n<p><\/p>\n<p>My goal is find the stress required to propagate the crack.
