Abstract One of the most commonly used methods in numerical solution of partial differential equations is the finite element method. In the finite element method, the region to be analyzed is divided into sub-sections called solution regions provided that the boundaries of the region are determined. This subdivision method depends on the type of differential equation to be solved. A variety of solution network production techniques are used to subdivide the solution region. By selecting the appropriate method, the solution region is divided into sub-compartments to ensure that the solution is faster and more accurate. The classical finite element method gives accurate results when instant analysis is performed on the solution area. However, in cases where partial differential equations change with time and solution network changes regionally, it is useful to use moving finite element method instead of classical finite element method. The use of a moving finite element method allows analysis to be carried out only in varying regions of the solution network to ensure rapid results. In this study, two dimensional solution network production techniques are mentioned. With the help of the developed program, regional changes on the solution network are explained in detail. As an application, C ++ based software was implemented.

Design and Analysis of a Vertical Pressure Vessel with Effect of Rotational Velocity on the Stresses and Deformation by using ANSYS

[Abdulfatai, A. Faro, Kazeem, K, Salam, Edith, E. Alagbe] Volume 6: Issue 3, Sept 2019, pp  110 - 120

DOI: 10.26706/IJAEFEA.2.6.20190702

Abstract In this study, the suitability and influence of Rotational Velocity (RV) on the operating conditions of a vertical Pressure Vessel (PV) was investigated. A vertical PV was designed and analyzed with the aid of ANSYS. Effect of eight different parameters on the performance of the designed PV was analyzed. The results obtained from designed PV using Finite Element Analysis (FEA) was validated by comparing it with that obtained from Manually Computed Method (MCM) and Utilization Factor (UF) method. The results of this investigation show that the designed PV was safe within the specified operating condition, the FEA results are more accurate than that of MCM and presence of RV affected the stress distribution and deformation of the PV.

Abstract The human teeth function is that to mechanically breakdown items of food by cutting and crushing them in preparation for swallowing and digesting. Tooth Development is complex process by which the teeth form from embryonic cells, grow into mouth. By significant amount of research in this field, it is widely accepted that there is most of factor within tissues that is necessary for development of teeth. Orthodontic dental implants have become a widely accepted treatment option for both partially and completely for lack amount of teeth’s in patients’ mouth. The clinical use of miniscrew anchorage includes some risks. Screw fracture might be one of the most undesirable side effects in clinical use of miniscrew anchorage. Orthodontic Implant Screw of Organization S.K. Surgical is undergoing failure at time of insertion. Failure of Implant Screw in jaw of patient is causing major problems like surgery for removal, long healing period of jaw, time and money wastage, loss of Reputation.
