The simulation for the situation of inverted T composite slab of precast fabricated construction is done, to analyze the stress distribution in the T composite slab of precast fabricated construction, shows that, the maximum deflection exhibits in the middle of plate. Due to the grouting of the concrete, the T plate and the concrete take effect simultaneously, to make the moment of inertia increase greatly, lower the deformation of the composite plate, and increase the resistance capacity. The T plate is pre-stressed, the stress in the x direction of steel bar will increase to the maximum value with the time pass. The result will give some guidance for the real practice.

The stress fields of rectangular and T shape compression dies were simulated by three dimensional photo-elasticity of stress freezing method. The rules of stress distribution of σx, σy, σz on the surface of rectangular and T-shaped dies were discovered, and the rules were also found inside the dies. The results indicate that the stress distribution of rectangular die is similar to that of T shape die. Obvious stress concentration in corner of die hole was observed. σz rises from die hole to periphery until it achieves maximum value then it diminishes gradually, and σz between die hole and fix diameter zone is higher than it is in other position. At the same time, the equations of stress field of extrusion dies were obtained by curved surface fitting experimental values in every observed point with multiple-unit regression analysis method and orthogonal transforms. These works can provide stress distribution model for die computer aided design and make.

The paper presents the theoretical foundations regarding the operational wear of rail heads. Rail, which constitute the basic element of the railway track, among others, guides the wheel in a lateral direction as well as enables a safe operation of rail vehicles. The criteria for the interaction of vehicles with the railway surface are described and the issues of interaction of the rail vehicle wheel with the rail is described. In the further part of the work an analysis of the influence of rail head wear of the 60E1 rail profile on the value of the moment of inertia Ix and sectional modulus Wx of this profile was carried out. The analysis was conducted on real, previously prepared samples of 60E1 operated rails. The methodology for calculating the geometric characteristics of cross-sectional characteristics of worn rails has been proposed using the Autodesk Autocad (Computer Aided Design software). The obtained values of moments of inertia and sectional modulus were compared with theoretical formulas described in the literature.

Composite slab by steel bar truss and concrete was a new style of floor slab. Because there were the small steel bar trusses in precast member, its short-term rigidity was higher than the normal composite floor slab. The structure was divide into four kinds, according to the relative location of the neutron-axis and the combined interface of slab; the relative value of the moment in first phase and the cracking moment of the precast slab. The different formulas to calculate short-term rigidity of precast member for four kinds were obtained. Through the models of composite slab by steel bar truss and concrete with different dimensions were established using finite element structural program, the formula feasibility was confirmed

Currently, the reforestation process has a number of disadvantages, such as the need to use manual labor during the distribution and planting of seedlings; mechanisms for planting seedlings are often equipped with tractors as traction means. The creation of furrows and the preparation of the soil immediately before planting affects the energy consumption of the implements’ drives. At the moment, the inefficiency of planting work is high, since the planting of seedlings with a closed root system occurs in conjunction with a plow. All these factors, when calculated for a long-term period, lead to greater energy consumption when carrying out this type of work. This article discusses approaches to the mechanization of the planting process. Using the experience of planting seedlings with a closed root system (CCS) manually and analyzing the methods of mechanization of planting, it is possible to obtain maximum efficiency when carrying out this type of work. Based on the material studied, a prototype of a planting device suitable for the technology of discrete planting of seedlings with ZKS was selected. Solid modeling of the working body in the Solidworks computer-aided design system has been carried out. When designing the model, the possibility of its production using additive technology using the FDM printing method was envisaged.

Dioscorea hispida is a poisonous plant normally found in forest where scientific studies have shown that its tuber contains toxic poison and can be consumed after its poison is removed. Traditionally the tubers were placed in flowing river water for several days. In the harvesting aspect, an innovative hand tool were conceptually designed to replace the traditional hoe or “cangkul”. Using IMADA digital force gauge to measure the force required for pulling out the tuber and reverse engineering methods, an innovative hand tool were designed and developed. The results from experiments showed that the force required for harvesting the Dioscorea hispida tuber is found significant with its weight versus regression squared (R2) of 0.86. The information of optimum force required from field experiment is used to model the simulation and practicality in Computer Aided Design (CAD) environment system. The finite element on stress distribution on selected material of hand tool was simulated by uploading the material characteristic on simulation program embedded in Solidworks software. The end result of the simulation is based on visualization of analysis in Solidworks while producing the hand tool for designing and fabrication from material which is lighter and stronger.

FEA is used in this research to describe the stress distribution of a seizure on a piston four stroke engine. Computer-aided design (CAD) software is used to do the finite element analysis. The major goal is to explore and analyse the thermal stress distribution of the piston during the combustion process in a real engine. The mesh optimization is described in this study, which uses a finite element analysis technique to anticipate the component's greater stress and critical region. The piston's upper end, which includes the piston head/crown, as well as the piston skirt and sleeve, is optimised to reduce stress concentration. The structural model of a piston will be developed using computer-aided design (CAD) and Pro/ENGINEER software. Furthermore, the finite element analysis was carried out with the ANSYS software.
