20.500.12556/DKUM-70781 Probabilistic study of the phenomenon of crushed grains using the model of Weibull Verjetnostna študija pojava drobljenja zrn po metodi Weibull The crushing of grains in a granular medium is a very important phenomenon; it is a source of both physical and mechanical changes to these materials. A statistical study of the mechanical properties of a material was used to characterize the distribution and fracture mechanics in order to quantify the evolution of these distributions with sample sizes (grains and whole grains). This work presents the results of an experimental study made on the crushing of individual grains of limestone and samples consisting of multiple grains subjected to a uniaxial loading in order to highlight the influence of the loading and the grain size on the rate of crushing. A statistical study using the Weibull method allowed us to model the problem and quantify the rate of breakage for the two cases. The results obtained show that the rate of deflection depends on the grain size and the intensity of the applied load. Statistical modelling using the Weibull method gave us acceptable results in both cases. Drobljenje zrn v pesek je pomemben postopek, ker povzroča fizikalne in mehanske spremembe materialov. Za določitev mehanskih sprememb je za porazdelitev zrn uporabljena statistična metoda, za določitev razvoja porazdelitve zrn (lomljenih in celih) v vzorcih pa mehanika loma. Delo je rezultat eksperimentalne študije drobljenja posameznih zrn apnenca ter večzrnatih vzorcev, ki so bili podvrženi enoosni obremenitvi, s čimer se je ugotovilo vpliv obremenitve in velikosti zrn na odnos lomljenja. S statistično metodo Weibull je problem modeliran in določen je odnos lomljenja za oba primera. Izsledki študije so pokazali, da je ocena odklona odvisna od velikosti zrn in jakosti obremenitve. Statistično modeliranje po metodi Weibull pa je v obeh primerih dalo zadovoljive rezultate. grain sample crushing statistical study drobljenje pesek statistična analiza modeliranje zrno vzorec drobljenje statistična študija true false true Angleški jezik Slovenski jezik Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru Znanstveno delo 2018-06-13 12:08:10 2018-06-13 12:09:24 2022-08-01 19:48:55 2019-07-11 18:19:40 2012 0 0 str. 51-61 št. 2 Letn. 9 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1854-0171 621.926 215987712 270616832 1854-0171 URN:SI:UM:DK:Y6LYWS6C Acta_geotechnica_Slovenica_2012_Toufik,_Bachir_Probabilistic_study_of_the_phenomenon_of_crushed_grains_using_the_model_of_weibull.pdf Acta_geotechnica_Slovenica_2012_Toufik,_Bachir_Probabilistic_study_of_the_phenomenon_of_crushed_grains_using_the_model_of_weibull.pdf 1 F543D162336EA8A45EE23BCAAC5DA9BA 5355aa6251f407aa7ab0f3a76d922af0b590a2021a5fdd96eff6a424ea1ef8c1 068ea063-7c10-11eb-bb7a-00155d0001ca 20.500.12556/dkum/2cb3d416-b9f9-402b-b5a4-2765cf0fd993 https://dk.um.si/Dokument.php?lang=slv&id=125593 http://fgserver3.fg.um.si/journal-ags/2012-2/article-5.asp 1 https://dk.um.si/Dokument.php?lang=slv&id=125594 Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Acta geotechnica Slovenica 0 0 0
