Yielding in the isotropic compression of Porto silty sandFerreira Amaral, Miguel (Avtor) Rios, Sara (Avtor) Viana da Fonseca, António (Avtor) , Fakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru (Lastnik avtorskih pravic) silty sandyield pointisotropic compressionhigh pressureseismic wavesThe yielding locus of a well-graded silty sand was analysed by means of isotropic compression tests and scanning electron microscopy (SEM). The tests were performed with precise instrumentation, for internal and external strain measurements, and shear-wave velocity measurements by means of bender elements. Finally, aiming at an accurate evaluation of the yield stress, four different methods were applied – two quite well know and the other two being innovative – leading to interesting conclusions.20122018-06-13 11:00:25Znanstveno delo70771ISSN: 1854-0171UDK: 550.34.01OceCobissID: 215987712COBISS_ID: 270574592ISSN pri članku: 1854-0171NUK URN: URN:SI:UM:DK:MBDSV74FslFakulteta za gradbeništvo, prometno inženirstvo in arhitekturo Univerze v Mariboru
