This article presents the gear modeling method in dynamic mechanical analysis using SPH (Smoothed Particle Hydrodynamics) analysis method. The parameter equations of the transition curve of gear root and the other parts of gear are decided. The 3D discrete particles model is established based on the parameter equations. The SPH pre-process program of global and local dividing is developed. The error between the divided discrete particles and theoretical profiles of the gear has been analyzed. The analysis results show that this modeling method is a relatively better method and the correct SPH discrete particles can be divided by this method.

Purpose The paper aims to construct a method to simulate the relationship between the parameters of soil properties and the area of sliding mass of the true slip surface of a landslide. Design/methodology/approach The smoothed particle hydrodynamics (SPH) algorithm is used to calibrate a response surface function which is adopted to quantify the area of sliding mass of the true slip surface for each failure sample in Monte Carlo simulation. The proposed method is illustrated through a homogeneous and a heterogeneous cohesive soil slope. Findings The comparison of the results between the proposed method and the traditional method using the slip surface with minimum factor of safety (FSmin) to quantify the failure consequence has shown that the landslide risk tends to be attributed to a variety of risk sources, and that the use of a slip surface with FSmin to quantify the consequence of a landslide underestimates the landslide risk value. The difference of the risk value between the proposed method and the traditional method increases dramatically as the uncertainty of soil properties becomes significant. Practical implications A geotechnical engineer could use the proposed method to perform slope failure analysis. Originality/value The failure consequence of a landslide can be rationally predicted using the proposed method.
