Abstract Based on hierarchic shape functions and an effective convergence procedure, the p-version and h-p adaptive analysis capabilities were incorporated into a finite element software system, called COSMOS/M. The range of the polynomial orders can be varied from 1 to 10 for two dimensional linear elastic analysis. In the h-p adaptive analysis process, a refined mesh are first achieved via adaptive h-refinement. The p-refinement is then added on to the h-version designed mesh by uniformly increasing the degree of the polynomials. Some numerical results computed by COSMOS/M are presented to illustrate the performance of these p and h-p analysis capabilities.

This article analyzes the first self-propelled floating dredging machine designed and executed by Agustín de Betancourt in 1810 to dredge the port of Kronstadt (Russia). With this objective, a study of computer-aided engineering (CAE) has been carried out using the parametric software Autodesk Inventor Professional, consisting of a static analysis using the finite element method, of the 3D model which is reliable under operating conditions. The results have shown that the system of inertia drums proposed by Betancourt manages to dissipate the tensions between the different elements, locating the highest stresses in the links of the bucket rosary, specifically at the point of contact between links. Similarly, the maximum displacements and the greatest deformations (always associated with these points of greater stress), are far from reaching the limits of breakage of the material used in its construction, as well as the safety coefficient of the invention, confirming that the mechanism was oversized, as was generally the case at the time. This analysis highlights the talent of the Spanish engineer and his mastery of mechanics, in an invention, the first of its kind worldwide, which served the Russian Empire for many years.

In the process of turning, pointing at the uncertain phenomenon of cutting which is caused by the disturbance of random factors, for determining the uncertain scope of cutting force, the integrated symmetric fuzzy number and the finite element method (FEM) are used in the prediction of cutting force. The method used symmetric fuzzy number to establish fuzzy function between cutting force and three factors and obtained the uncertain interval of cutting force by linear programming. At the same time, the change curve of cutting force with time was directly simulated by using thermal-mechanical coupling FEM; also the nonuniform stress field and temperature distribution of workpiece, tool, and chip under the action of thermal-mechanical coupling were simulated. The experimental result shows that the method is effective for the uncertain prediction of cutting force.

With the port crane getting bigger and heavier, and also moving much faster than before, the thermal effect in wheel and rail during the brake process can be a reason of the failure of port crane. In this paper, the thermal effect during the brake process of port crane is studied using the finite element method. Based on the finite element model, the ANSYS10.0 finite element software is used. The thermal effects under different coefficients are discussed. Three different slide speed of wheel, two different loads of crane, and three different frictional coefficients are applied. The importance of the different coefficients is obtained from the numerical results.

The finite element 3D model of heavy rail roller complex straightening is established by the finite element method in this paper.The straightening process is optimized by orthogonal experimentation and regression analysis. The formative mechanics and the regulation of the residual stress in the process of straightening are researched. The results of the simulation show that: whatever is on the basement of the residual stress or flatness, the new schedule is better than the real field one, residual stress is controlled within 250Mpa.

The high-pile wharf near estuary under wave subjects to great wave force. The wave force can cause destruction of the wharf superstructure. Current research focuses on the case where the forward direction of the wave is perpendicular to or inclined to the wharf front line and mostly applied physics modelling experiments. This paper is to study the case where the wave is parallel to the front line of the high-pile wharf. Take a high-pile wharf near estuary as a model and use the finite element software Ansys to establish the space model. Analysis of internal forces and the destruction of high-pile wharf are made. Meanwhile, the preliminary solution depending on the destruction are proposed, providing references for projects.

This paper investigates the performance of conventional turning and ultrasonically assisted turning (UAT) processes with plane and textured cutting inserts. Simulations based on the finite-element method were carried out using a software package ABAQUS/Explicit (Dassault Systemes, France). The obtained results were validated experimentally by employing a specially developed UAT setup. The purpose of the paper is to analyze cutting-force variation by the use of textured cutting inserts. Optimized dimensions of the texture pattern were used to model textured cutting inserts. The cutting-force variation in UAT was assessed with finite-element method, confirming diminishing cutting forces at a tool–workpiece interface during a noncontact time. The use of the textured cutting inserts in the UAT process resulted in the lowest cutting forces when compared to a plane tool in UAT as well as both plane and textured tools in the conventional turning process.

The reactance of the transformer windings is an important component for the design which has a direct effect on its operation. Reactance is used for computation of not only the transformer equivalent circuit parameters and also for designing its protection. The Roth’s method, Rabin method, method of images, and classical methods are the traditional methods used for its calculation. The finite element method can be used for the calculation of transformer reactance. In the industrial revolution 4.0 all manufactured transformers would be evaluated through their 3D design and performance analyzed by computational methods. In this work the reactance calculated by the finite element method has been compared to that calculated by the classical method. The calculated values of energy stored in the windings and other parts and the reactance can be found.
