Abstract: The article is deals by an introduction to the theory of impact load for thin plates. This is the plates that are characterized by a structure which is bounded by upper and lower surface plane. These surfaces are spaced by a distance h, which is substantially smaller in comparison which other dimensions of the plate (a × b). The impact causes a deformation of the plate which is vibrated. The deformation is only within the limits of Hook's law. Therefore there is not permanent deformation of the plate. In the plate is induced shear stress, bending stress and shear forces. The second part of the article is focused on the numerical solution of thin isotropic aluminium plate which is made from AL 99.9. This plate has a dimension of 100 × 100 × 2 mm. It was solved the deformation of the plate after the impact load which were produced in the centre of the plate by FEM in software ADINA. By results was a graph of the deformation, velocity and acceleration of response wave in the material.

Abstract: Friction stir welding is one of the newest methods of metal welding. The method is constantly being developed and friction stir spot welding (FSSW) is one of its varieties. The method is mainly used in the aircraft, automotive and shipbuilding industries. During the process, heat is generated as a result of friction between the tool and materials as well as plastic deformation of the joined materials. The paper presents a numerical analysis of welded structures made of 6061-T6 aluminium alloy. The specimens were joined by refill FSSW. This method joins metals in a solid state. The numerical calculations were performed using the ADINA System based on the finite element method. The sheets were modelled with shell elements and the joints were modelled with 3D-solid elements. The experimental investigations were carried out using a non-contact system allowing for measuring displacements and strains in real time. The numerical results were compared with the test ones. The structures were assessed regarding strength and the possibility of their application in the aircraft industry.

Abstract: Establish the finite element model of the large LNG storage tanks in Dongjiakou with ADINA, using different frequency and damping ratio of laminated rubber bearings as isolation device of tanks. Compare the effect of different isolation frequency and damping ratio to the tanks under earthquake. The results show that the greater the isolation frequency and damping ratio, displacement of internal and external tank, acceleration and control effect of liquid sloshing wave height more obvious, but the base shear, base overturning moment and dynamic fluid pressure will increase. So when selecting isolators, consider aspect ratio of tanks, isolation frequency, damping ratio and other parameters comprehensively, select the optimal combination to achieve the best damping effect.

Abstract: The Diaphragm Chamber is a critical component in fluid end of large scale diaphragm pump. Static strength failure and fatigue failure of diaphragm chamber are caused by high pressure of slurry flowing which is transported by diaphragm pump. It is necessary to analyze the inferences of different boundary shapes of diaphragm chamber on its static strength. In this paper, diaphragm chamber was simulated by finite element analysis program ADINA. Inferences of different boundary dimensions of diaphragm chamber on its strength are studied. Stress distribution graphs of diaphragm chamber can be obtained from analysis results. Maximum stresses of diaphragm chamber affected by different boundary shapes of diaphragm chamber are summarized. The analysis results in the paper provide some theoretical guidance for structure optimum of diaphragm chamber and manufacturing cost reduction.

The method of finite spheres in three-dimensional linear static analysis

Lai, B., Bathe, K.J.

Massachusetts Institute of Technology, Cambridge, MA 02139, United States

Computers and Structures: Volume 173, 1 September 2016, Pages 161-173

Abstract: The objective of this paper is to assess the reliability and effectiveness of the method of finite spheres, a truly meshless overlapping finite element method, for the solution of practical three-dimensional linear elasticity problems. Advantages include simplified discretization and the elimination of element distortion. The method is implemented in the ADINA finite element program through a user-supplied element subroutine. The solutions of three increasingly complex three-dimensional problems are studied (1) to establish the reliability of the method for practical linear elasticity problems and (2) to assess the effectiveness of the method as compared to the standard finite element method. The solutions indicate that the method of finite spheres is between one and two orders of magnitude more expensive in computational time than the standard finite element method. This is still a promising result since there are significant time savings for the method of finite spheres during the pre-processing phase, particularly in the discretization of complicated three-dimensional geometries and because the overlapping sphere elements can be directly coupled to traditional finite elements.

Abstract: The application of a novel cement-based piezoelectric (PZT) ceramic sensor to the in-situ stress-time history monitoring of a reinforced concrete frame structure is described in this article. Smart frame composite structures were produced and characterized by a range of experimental methods. ADINA, a finite element analysis program, was used to analyze the mechanical response of the concrete frame under static loading. The results show that the mechanical-electrical response of sensors embedded in a reinforced concrete frame structure follows a linear relationship under various loading conditions. The sensors are able to record the stress history of the frame under static loads. Moreover, the measured stress maxima agree well with the simulated results, and the smart structure is found to be capable of reliably monitoring the response of a frame structure during stress testing for different loading modes to real concrete structures. The study indicates that such cement-based PZT composites have a high feasibility and applicability to the in-situ stress-time history monitoring of reinforced concrete structures.

Abstract: The studies on the lateral-torsional buckling of cantilever steel beam with tip lateral elastic brace are rarely reported. The total potential energy is first established for the lateral-torsional buckling of cantilever steel beam with tip lateral elastic brace under uniform and concentrated load. The modal trial function of the lateral displacement and torsional angle are expressed as trigonometric function combination with six terms. By introducing new dimensionless parameters, the analytical solution of the dimensionless buckling equation for the lateral-torsional buckling of cantilever steel beam with tip lateral elastic brace is obtained. With the help of 1stOpt software which is mathematical optimization analysis software, the non-dimensional critical moment formula of the lateral-torsional buckling of cantilever beam with tip lateral elastic brace is obtained. Then, the accuracy of the formula is verified by ADINA finite element software. The results show that the given critical moment formula is of high accuracy. It provides convenient and simple design method for practical engineering.

Journal of Engineering Science and Technology, Volume 11, Issue 12, December 2016, Pages 1669-1677

Abstract: A nonlinear finite element analysis of steel fibre-reinforced concrete beams subjected to static loading was explored using ADINA software. A predefined 3D model of concrete beam of dimension 100 mm×100 mm×500 mm was prepared using the smeared crack approach to fracture of concrete in the mode I; this model simulates a nonlinear response in tension. Stress redistribution was performed by the equilibrium iterations process. Both stresses and displacements occurring at different node locations of the element were carefully examined. In addition, the results of laboratory experiments conducted on concrete beams with a fibre content of 60 kg/m3 based on volume (that is: 0.75% and 1% by volume of concrete) were compared to the analytical results in order to ascertain the consistency of the results. It was realized that the interfacial bond between the concrete and the fibres has a significant effect on the overall performance of the strengthened members.

Abstract: The silicon carbide cladding concept is currently under investigation with regard to increasing the accident tolerance and economic performance of light-water reactor fuels. In this work, the stress fields in the multi-layered silicon carbide cladding for LWR fuels are calculated using the commercial finite element analysis software ADINA. The material properties under irradiation are implemented as a function of temperature. The cladding is studied under operating and accident conditions, specifically for the loss-of-coolant accident (LOCA). During the LOCA, the blowdown and the reflood phases are modeled, including the quench waterfront. The calculated stresses along the cladding thickness show a high sensitivity to the assumptions regarding material properties. The resulting stresses are compared with experimental data and the probability of failure is calculated considering a Weibull model.
