Research ArticleOpen accessPhrase in the titleEvaluating the Effect of Soil Particle Characterization on Internal Friction AngleArezou Rasti, Hamid Ranjkesh Adarmanabadi, Maria Pineda, Jesse ReinikainenOne of the critical design parameters used in evaluating soil structure is the friction angle, derived from Mohr's Circle failure criterion. The soil friction angle is an engineering parameter estimated in the laboratory to quantify the soil shear strength in geotechnical applications. This paper indicates an experimental study investigating the impact of particle size on different sandy soils shear strength … …American Journal of Engineering and Applied Sciences, Vol. 14, Issue 1 · 21 Feb 2021 · 8,890 accessesView PDFCite
Research ArticleOpen accessIn the abstractParameter Measurement and Calibration in Discrete Element Simulation of Broken Sweet Potato SeedlingsGuizhi Mu, Xieteng Qi, Wangzhi Zhang et al.Given the lack of accurate parameter values in discrete element simulation of sweet potato seedling mechanized recovery, a direct measurement and virtual calibration method was used to study the Discrete Element Method (DEM) simulation parameters of broken sweet potato stems and leaves. The intrinsic parameters, collision recovery coefficient and static friction coefficient of broken seedlings were acquired by physical experiments. … …American Journal of Biochemistry and Biotechnology, Vol. 17, Issue 2 · 8 Jun 2021 · 6,369 accessesView PDFCite
