Hole shapes and their locations in lotus roots were studied and presented in this paper. The finite element method was used to study the effect of several factors on the structural integrity of a lotus root-like component. The factors considered in this paper include hole shape, number, size and location. The analysis of different structures was carried out using ANSYS software and assuming a porosity of 20% for each case. Stress values, effects of each factor and interactions between factors are discussed in the paper. The results from the analysis showed that engineering component design can be inspired by the lotus root which has several holes of different shape and size.

The Finite Element Model

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 article presents solutions to the problem of rod buckling, taking into account creep effects. Trigonometric series, the finite difference method in combination with the programming language MATLAB, as well as the finite element method in the ANSYS software package were used in the solutions. The behavior of the rods is researched for two types of relations between strain and stress during creep, with strains in an explicit and implicit form. When solving, the criterion of initial imperfections with their different values is used, as well as the tangential-modular theory. The results obtained for the two creep models are compared. The conclusion is made about the accuracy of the results of calculations in ANSYS with the presence of a combination of geometric and physical nonlinearity for various creep models.

Currently, wind energy in Mexico is growing and the same is happening worldwide, so projects with national technologies for the manufacture of wind turbine components must be developed. In this work, a proposal is made for the design of the hub of the rotor for a 50-kW turbine, the objective is to make a new proposal to improve the previous design of project P07 of the Centro Mexicano de Innovación en Energía Eólica (CEMIEEólico), which has a welded mechanical hub for a prototype turbine 30 kW. In addition, a simulation is performed through analysis of the finite element method (FEA) by applying certain load elements with the simplified load method of the international standard IEC 61400-2. In these simulations, the load cases of the norm that directly influence the cube are analyzed, then simulated in the ANSYS software to validate the proposed design, mainly analyzing the stresses and deformations. The results obtained will serve as a reference to manufacture the cube and evaluate the feasibility of carrying out a commercial stage with a view to making national components for wind farms.

This paper is devoted to the derivation of material indices using the finite element method. Material indices take into account material properties such a Young’s modulus and density are a powerful tool for material selection for various applications since they allow a quick comparison of suitability of different materials. Until now material indices were developed analytically for rather simple textbook-like examples. However, by implementing the finite element method and data fitting tools material indices can be developed for more complicated problems where the analytical solution cannot be obtained. The current paper describes derivation of material indices using ANSYS software. It is used as a simulator of a physical phenomenon. The simulation generates output data which is used to derive the material index.

Методом конечных элементов с помощью программного комплекса ANSYS проведен анализ влияния дефекта основного металла типа «расслоение», в зависимости от глубины его залегания, на возможную безопасную эксплуатацию технологического оборудования. По результатам исследований установлено, что расслоение не оказывает существенного влияния на несущую способность оборудования, пока оно локально и не распространяется. The analysis of the influence of a base metal defect of the "stratification" type, depending on the depth of its occurrence, on the possible safe operation of technological equipment was carried out by the finite element method using the ANSYS software package. According to the results of the research, it was found that the stratification does not significantly affect the load-bearing capacity of the equipment, as long as it is local and does not spread.

In this paper, the tensile-compression prestressed concrete beam was researched, and gets deflection of the beam subjected to load. Then, the beam was analyzed by the finite element method of ANSYS software. The test and analysis results show that the beam has a good flexibility and the phenomenon of stress concentration were appeared in ends concrete of pre-compressed steel tube. The pre-compressed steel tube control stress is 0.5 times the nominal value of steel tube, the concrete pre-tensile stress can be obtained effectively by relaxes pre-compressed steel tube. This paper further optimizes the dosage of pre-tensile tendon (Ap), pre-compressed steel tube (AT), tensile reinforcements (As)and compression reinforcements (A`s).The results from example show that the concrete structure of tensile-compression prestressed can reduce the pressure area height of the beam effectively and solving conventional prestressed concrete structure excessive or cannot reinforcement in pressure area.
