Air flow field around open storage pile is a matter of flow around square cylinder. Prediction of wind flow over storage pile plays a dominant role in the evaluation of its environmental impact. Numerical simulation of flow around square cylinder has been widely recognized as a powerful tool in determining air flow field. This paper introduces the application of the numerical simulation in the research...
Root system of vegetation can improve slope stability through changing in mechanical and hydrological properties of root-soil matrix. In this paper, the typical models to describe the mechanical effect in soil-root system and some theories of numerical simulation on root reinforcement mechanism are briefly elucidated, Based on the Strength Reduction Method(SRM) and ABAQUS code, a numerical model is...
Based on the fact that a static problem has an equivalent wave speed of infinity and a dynamic problem has a wave speed of finite value, an effective loading algorithm associated with the explicit dynamic relaxation method was presented to produce meaningful numerical solutions for static problems. The central part of the explicit dynamic relaxation method is to turn a time-independent static problem...
