effect of particle crushing on shear strength and dilation characteristics of sand-gravel mixtures
there are limitations in experimental studies on sand-gravel mixtures due to the small size of testingspecimens. due to this problem, many researchers have worked on prediction of the shear strength of mixture by testingthe sandy fraction of soil alone and developed empirical relationships. most of the previous relationships have beendetermined for low surcharge pressures in which particle brea...
متن کاملParticle-scale mechanics of sand crushing in compression and shearing using DEM
In this paper, the discrete element method is used to explore why differing amounts of breakage, quantified using Hardin’s relative breakage parameter (Br), are associated with the critical state line (CSL) and the normal compression line (NCL) at similar stress levels. Virtual samples initially containing more than 20,000 spherical particles were isotropically compressed to a range of confinin...
متن کاملAn Elastoplastic Model Considering Sand Crushing
The behavior of sand crushing will appear when the confining pressure is up to a certain value, which results in disappearing of the positive dilatancy of sand. Adopting a new hardening parameter with the crushing stress, an elastoplastic constitutive model considering sand crushing is proposed. Comparing the conventional triaxial compression test results with the model prediction, it shows tha...

15 صفحه اولVariation characteristics of chlorophyll fluorescence of a typical Eremophyte (Smirnovia Iranica (Sabeti)) during phenological stages in the sand drift desert (Case study: In Kashan Region)
Smirnovia iranica, a native valuable woody species from Fabaceae, is an adaptable plant of central sandy areas of Iran. Changes in chlorophyll fluorescence and photosynthetic pigments characteristics were analyzed in the course of phenological stages including vegetative, flowering, seed ripening, and seed falling stages, respectively (VS, FS, SRS, and SFS). The results obtained from analysis o...
