20.500.12556/DKUM-70523 Modeling of the stress-strain behavior in hard soils and soft rocks Modeliranje napetostno-deformacijskega obnašanja mehkih kamnin in trdih zemljin The paper begins with a definition of hard soils and soft rocks (HSSR); this is followed by a short overview of the typical stress-strain behavior of HSSR. It is shown that in spite of the differences in the origin, type and strength of materials, similar stress-strain behaviors can be observed for different materials, ranging from soils to rocks. Based on this observed similarity a theoretical framework can be postulated, with which an appropriate constitutive model for HSSR can be formulated. This model includes the concepts of structure and destructurization as intrinsic material properties. A model named S_BRICK that takes into account the structure and destructurization has been developed and a comparison of this model’s predictions with laboratory results is presented. V prispevku je uvodoma predstavljena osnovna definicija mehkih kamnin in trdih zemljin. V nadaljevanju je nato predstavljeno značilno napetostno-deformacijsko obnašanje mehkih kamnin in zemljin, kjer bo prikazano, da se materiali z različno sestavo in genezo v pomembnih vidikih obnašajo podobno. To omogoča postavitev teoretičnega okvirja, znotraj katerega je mogoče ustrezno formulirati in postaviti konstitutiven materialni model, ki opisuje njihovo obnašanje. Ključen element za postavitev teoretičnega okvirja in konstitutivnega modela je vpeljava koncepta strukture in destrukturizacije. V zaključku je na kratko predstavljen konstitutivni model za mehke kamnine in trde zemljine S_BRICK, ter rezultati primerjave napovedi modela z rezultati laboratorijskih preiskav. geomechanics soft rocks hard soils stress-strain behaviour constitutive modeling structure destructurization numerical modeling geomehanika mehke kamnine trde zemljine napetostno-deformacijsko obnašanje konstitutivni modeli S_BRICK BRICK struktura destrukturizacija numerično modeliranje true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-05-18 10:17:12 2018-05-18 10:17:51 2022-08-01 19:27:05 2019-07-11 18:10:09 2007 0 0 str. 4-15 št. 2 Letn. 4 2007 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 624.131 215987712 1330915 1854-0171 URN:SI:UM:DK:MB6PN4MH Acta_geotechnica_Slovenica_2007_Vukadin_Modeling_of_the_stress-strain_behavior_in_hard_soils_and_soft_rocks.pdf Acta_geotechnica_Slovenica_2007_Vukadin_Modeling_of_the_stress-strain_behavior_in_hard_soils_and_soft_rocks.pdf 1 BE8108B426C49AC6A895FBE620C1E228 118ffcc360f92452d305a05e492ad220af8824e0ea4433dd6ee22ed067722922 f7a589e7-7c0f-11eb-bb7a-00155d0001ca 20.500.12556/dkum/b6cd2e26-4c7f-402a-9af4-533e7b524da8 https://dk.um.si/Dokument.php?lang=slv&id=124839 http://fgserver3.fg.um.si/journal-ags/2007-2/article-1.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=124838 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
