With the increasing requirements of environmental protection, the slope reinforcement method is becoming environment-friendly. In recent years, more and more attention has been paid to the study of slope reinforcement by vegetation, and the mechanism of vegetation reinforcement has been initially established, but it is not common to study vegetation reinforcement by numerical reappearance. On the basis of reviewing the mechanism of slope reinforcement by vegetation, this paper studies the vegetation reinforcement scheme of a slope by finite element method. The results show that the finite element method can be used for vegetation reinforcement simulation, and the simulation results are combined with reality. The method in this paper provides a reference for the analysis of similar problems, and also provides a reliable analysis tool for the analysis of slope reinforced by vegetation.

A numerical model was made to establish the casting hardness for the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn1. Computer simulation of hardness was performed using the finite element method in ANSYS environment, and the hardness values were obtained by experiments based on the Rockwell method. The showed model fulfils the initial criteria, which provides with the basis for the assumption about its utility in establishing the casting hardness of the magnesium alloys MCMgAl12Zn1, MCMgAl6Zn1, MCMgAl3Zn1 and MCMgAl9Zn., using the finite element method within the framework of the ANSYS program. There is the correlation of the computer simulation results with the experimental outcomes. Nowadays the computer simulation is very well known, and it is based on the finite element method, what it makes possible to better comprehend the autonomy between the process parameters and selected optimal solution. The chance of applying faster and faster calculation machines and the formation of much software enables creating the more accurate models and more the adequate ones to reality.

The friction holding effect and the friction reducing effect occurring during Hydraulic Deep Drawing and the pre-bulging resulting in more plastic deformation on products are applied on sheet hydro-forming. For Hydraulic Deep Drawing of a square cup, the thickness distribution and the relation between the height and the pressure of pre-bulging are simulated with SPCC steels as the specimen by the finite element method. An experimental apparatus of sheet hydro-forming has been constructed to carry out the hydraulic deep drawing experiments of square cups. Experimental thickness distribution and punch load are compared with simulation results. Good agreement was found. The flow patterns of the circular and square blanks with the condition of being firmly pressed against the punch observed from the experiments are in agreement with the predicted results.Keywords:Hydraulic Deep Drawing, sheet hydro-forming, finite element method

Modal analysis provides the dynamic behavior of an object or structure, and is often undertaken using the Finite Element Method (FEM) due to its ability to deal with arbitrary geometries. This article investigates the use of Augmented Reality (AR) to provide the in situ visualization of a modal analysis for an aluminum impeller. Finite Element Analysis (FEA) software packages regularly use heat maps and shape deformation to visualize the outcomes of a given simulation. AR allows the superimposition of digital information on a view of the real-world environment, and provides the opportunity to overlay such simulation results onto real-world objects and environments. The presented modal analysis undertaken herein provides natural frequencies and the corresponding deformation of an aluminum impeller. The results indicate the ability for the design part and finite element analysis results to be viewed on the physical part. A mobile AR-FEA-based system was developed for Modal Analysis result visualization. This study offers designers and engineers a new way to visualize such simulation results.

The roll-on process of the ship loader is studied with the finite element method in this paper. The principle and the scheme of the parametric modeling for the ship loader have been discussed. The vibration frequency and the vibration mode of the ship loader in the roll-on process have been researched, and the weaknesses in the structure of the ship loader have been founded. Based on the above discussion, the reinforcement scheme of the ship loader has been put forward, and the vibration mode and frequency of the strengthened ship loader in the roll-on process have been analyzed. With the comparison of the original one, the anti-vibration performance of the strengthened ship loader has been improved, the reinforcement scheme has been proved to be a worthy one in the roll-on process.

The work employs the finite element method to model the finger touch on the flexible ultra-thin touch panel for analyzing the touch signal. The touch signal generates the ghost points when the fingers multi-touch on the flexible ultra-thin touch panel. The simulation of minimizing the top layer (over cover) thickness based on the model is conducted in order to eliminate the ghost points. The simulation results show the over cover thickness should be larger than 107 μm to eliminate the ghost points. Further, we propose the method to solve the ghost points and minimize the over cover thickness. The simulation results conducted in this proposed method show that the over cover thickness can be reduced further to 65 μm.

Compression behavior of a novel type of SiC/Al co-continuous composites was investigated using the finite element method and a new constitutive model were presented in this paper. The results show that the new constitutive model of the co-continuous composites can predicate the compression behavior of the composites accurately according to the simulative data. The fitting curve of the compression behavior achieved from the constitutive formula accords with the simulation results, which improves the reliability of the simulation on composites.
