Matlab tools are used to improve the programming in the process of calculation and analysis by adopting the continuous and discrete numerical methods developed in modern times with the variational principles and the subdivision interpolation as the basis, so as to implement the finite element analysis of the module, which is one of the most important method to solve the calculation and analysis in the calculation of complex engineering by finite element method. Firstly, according to the development of finite element method, and the characteristics of point process, we analyze the fundamental characteristics of the finite element method. On the basis of this, combined with the Matlab visual programming GUI component, we has designed the improved calculation and analysis programming of finite element method. In order to verify the rationality of the process, triangular unit division method is used to carry out the empirical analysis. And the results show that this method is effective, and has very strong practicability.

Within this article, there are presented a series of researches that were developed for the first time in Romania, in the field of customized medical implants made by using the Selective Laser Melting (SLM) technology. Finite Element Method (FEM) has been successfully used in order to analyze the fatigue and to determine the durability of a customized medical implant that has been selected for the made analysis. The material characteristics taken into consideration within the Finite Element Analysis (FEA) that has been performed were the ones of two types of dedicated metallic powders which are commercially available (TiAl6Nb7 and TiAl6V4 material) and suitable for the SLM 250 HL equipment from the SLM Solutions GmbH Company from Lubeck, Germany. The Finite Element Analysis made in the case of these two types of SLM titanium alloyed materials, proved that the modified characteristics, such as the yield strength and hardness of the material are significantly influencing the durability of the medical implants made by SLM technology.

Based on actual working conditions and parameters of the rudder system, the purpose is optimizing the connection of rudder system by keyless coupling technology. Analysis on the keyless coupling of rudder system is done by the finite element method under impact loads in different directions. It can improve the performance of keyless coupling in the specific operation conditions of rudder system to be excellent. According to the test requirements of the torque and impact, the results of the completion of the finite element analysis are verified by establishing the experimental platform of keyless coupling. Experiments and analysis of the results show that the preload is formed by the hydraulic nut in the keyless coupling and the static frictions is formed between the rudder and tiller. In the meantime, it is formed between rudder and the rudder blade which can make the working state of the rudder system stable under the required torque and impact loads.

Abstract The paper describes the intention of the authors to determine whether it is possible to predict relative belt edge endurance for radial passenger car tires using the finite element method. Three groups of tires with different belt edge configurations were tested on a fleet test in an attempt to validate predictions from the finite element results. A two-dimensional, axisymmetric finite element analysis was first used to determine if the results from such an analysis, with emphasis on the shear deformations between the belts, could be used to predict a relative ranking for belt edge endurance. It is shown that such an analysis can lead to erroneous conclusions. A three-dimensional analysis in which tires are modeled under free rotation and static vertical loading was performed next. This approach resulted in an improvement in the quality of the correlations. The differences in the predicted values of various stress analysis parameters for the three belt edge configurations are studied and their implication on predicting belt edge endurance is discussed.

Abstract The finite element method has been used widely in tire engineering. Most tire simulations using the finite element method are static analyses, because tires are very complex nonlinear structures. Recently, transient phenomena have been studied with explicit finite element analysis codes. In this paper, the authors demonstrate the feasibility of tire cornering simulation using an explicit finite element code, PAM-SHOCK. First, we propose the cornering simulation using the explicit finite element analysis code. To demonstrate the efficiency of the proposed simulation, computed cornering forces for a 175SR14 tire are compared with experimental results from an MTS Flat-Trac Tire Test System. The computed cornering forces agree well with experimental results. After that, parametric studies are conducted by using the proposed simulation.

To research the load upper bracket of Francis hydroelectric unit, then established the finite-element model, and analyzed the structure stress of 7 operating condition points with the ANSYS software. By the strain rosette test, acquired the data of stress-strain in the area of stress concentration of the upper bracket. The inaccuracy was considered below 5% by analyzing the contradistinction between the finite-element analysis and the test, and match the engineering precision and the test was reliable. The finite-element method could be used to judge the stress of the upper bracket, and it could provide reference for the Structural optimization and improvement too.

The natural frequencies of circular saws limit the operating speeds of the saws. Current industry methods of increasing natural frequency include pretensioning, where plastic deformation is induced into the saw. To better model the saw, the finite element model is compared to current software for steel saws; C-SAW, a software program that calculates frequencies for stiffened circular saws. Using C-SAW and the finite element method the results are compared and the finite element method is validated for steel saws.

Nowadays, materials used to construct house or building wall areconsidered not only in the physical material behaviour but also energy conscious and economic factor. Adding crumb rubber to the brick composite is one of many methods to develop the properties of bricks. As widely known,the finite element method (FEM) is a tool used for finding accurate solutions of the heat transfer equation of materials including the composite bricks. In this paper an investigation of the heat transfer of a soil cement brick containing crumb rubber particles, is presented and compared to results of finite element analysis (FEA) simulation. To determine the effect of crumb rubber to the heat transfer behaviour of soil cement brick, different volume fractions are varied by 10, 20, 30 and 40%. It was reported that a modelling application reveals good correspondence with the experimental results.
