3D DEM Analysis of Particle Breakage Effect on Direct Shear Tests of Coarse Sand

چکیده
This paper explores the effect of particle breakage on mechanical behavior coarse sand through 3D Discrete Element Method (DEM) simulations direct shear tests (DST). The objective is to gain insights into macro- and micro-mechanical behaviors crushable sand, with a particular focus stress–strain relationship, volumetric deformation, evolution grain crushing. involve comparison between non-crushable models, where particles are implemented in zone DST subjected different high normal stresses. findings indicate that experience partial crushing at peak stress, further leading production finer shearing plane during critical state. migration these under pressure gravity generates their accumulation predominantly lower section simulation box. Importantly, presence induces decrease stress an increase strain contractive instead dilation, which gradually stabilizes deformation higher

this experimental study has been conducted to test the effect of oral presentation on the development of l2 learners grammar. but this oral presentation is not merely a deductive instruction of grammatical points, in this presentation two hypotheses of krashen (input and low filter hypotheses), stevicks viewpoints on grammar explanation and correction and widdowsons opinion on limited use of l1...
