“…Although SPH is an effective numerical method to perform the large failure analysis of soil slope, the numerical instability of SPH may result in unrealistic fracture and particle clustering in simulation. Zhang et al [5] studied the stability and large deformation failure of the soil slope using the reproducing kernel particle method (RKPM). This simulation showed that RKPM is suitable for the extremely large deformation problem of slope failure.…”

The failure analysis of the soil slope is a very important topic in the field of geomechanics. Being a fully Lagrangian particle method, the material point method (MPM) has distinct advantages in solving the extremely large deformation problem. For both cohesive and noncohesive soil slopes, the large deformation failure problems are analyzed using MPM and the Drucker-Prager constitutive model. For verification of the numerical method, the comparison between MPM and analytical solutions of the dam break problem is presented. Moreover, the numerical results by MPM are compared with the experimental results for the collapse of the aluminum-bar assemblage. Simulations reveal the cohesive soil slope under gravity has a shear band failure mode. Computational results show the reposed angle of non-cohesive soil slope is less than the internal friction angle, and the reason for this phenomenon is presented. The purpose of this study is to give a further understanding of the slope failure in different soil types and provide a computational tool for the failure analysis of soil slopes.

A simple, rapid method was developed using on-line high-performance liquid chromatography (HPLC)-diode array detection (DAD)/electrospray ionization mass spectrometry (ESI-MS) to simultaneously analyze multiple bioactive constituents in the extract of Rheum tanguticum Maxim. ex Balf. (Dahuang), a traditional Chinese medicine (TCM). Many bioactive constituents gave prominent [M-H]- ions in the negative ion ESI mass spectra. Among them, 41 different constituents including 16 anthraquinone derivatives, 7 phenylbutanone glucopyranosides, 4 stilbenes and 14 tannins were unambiguously identified or tentatively characterized based on their retention times, UV spectra and mass spectra in comparison with the data from standards or references. Meanwhile, some principles of fragmentation behavior for different types of constituents were proposed, which could contribute to the elucidation of these constituents in Rheum tanguticum.

“…In the current research on plastic cylinder head covers, Y. Charles Lu et al studied the effect of the transfer path on the vibration of plastic cylinder head covers [4]. Zheng Kang et al studied and optimized the sound quality of the plastic cylinder head cover of an engine [5], and the relationship between the transmitted noise of the plastic cylinder head and the radiated noise of the structure [6]. There are few studies specifically focusing on the influence of the structural design of plastic cylinder head cover on NVH performance.…”

Based on characteristics of plastic head cover, the paper carried out 5 design concepts to improve its NVH property. It’s useful to improve NVH properties of product if follow the concept when design or optimize a head cover. In this paper, finite element and multi-body dynamics analysis methods were used to analyse a plastic head cover firstly. At second the head cover was optimized with the concept in the process. Finally, the plastic head cover met the development target. Test results proved the reliability of design concepts as well.
