Item Metadata only Two-dimensional direct current resistivity inversion : finite element method(Mahidol University. Mahidol University Library and Knowledge Center, 2007) Songkhun Boonchaisuk; Weerachai SiripunvarapornItem Metadata only Biomechanical evaluation of splinted 4- and 6- millimeters short dental implants with different crown-implant ratios, a finite element analysis(Mahidol University. Mahidol University Library and Knowledge Center, 2024) Salaorat Bunnag; Piyapanna Pumpaluk; Surakit Visuttiwattanakornto the implant abutment and periimplant structures, using a three-dimensional finite element method. Dental implants and abutments were scanned, and the scans were analysed using NX Nastran software to create finite element models. A total of 48 experimental... states from 12 finite element models were initiated with different conditions according to diameter, length, crown height, and direction of the occlusal force. The results showed that crown height did not influence the stress concentration on implantPublication Metadata only A study of mechanical property of Eggshell with inverse method and finite element analysis(2018-01-01) Jetsadaporn Priyadumkol; Chakrit Suvanjumrat; Mahidol University© 2018 Trans Tech Publications, Switzerland. This research proposed an inverse method to calculate the mechanical property of a chicken eggshell. The optimization method had been performed to determine the simulated results of the finite element... calculation method between the inverse method and finite element method was less than 0.1%. Consequently, the inverse method and finite element analysis can be used to determine the mechanical property of the other eggshell types in the further work.Item Metadata only Mathematical modelling of fluid flow and heat transfer under electromagnetic force in the continuous steel casting process(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Jutatip Archapitak; Benchawan WiwatanapatapheeItem Metadata only A mathematical model and numerical solutions of wave propagation in shallow water(Mahidol University. Mahidol University Library and Knowledge Center, 2004) Sineenart Srimongkol; Benchawan WiwatanapatapheePublication Metadata only Heat transfer efficiency analysis of infant radiant warmer by 3D finite element method(2012-12-01) K. Roongprasert; P. Phasukkit; S. Airphaiboon; C. Pintavirooj; N. Thongpance; A. Sanpanich; King Mongkut's Institute of Technology Ladkrabang; Rangsit University; Mahidol UniversityThis paper presents heat transfer from infrared element source from infant radiant warmer. The principles of thermal radiate using three-dimensional finite element methods is show the efficiency and effect of Infant radiant warmer. In the design... finite element methods simulation as close to the true result. The results come in the form of temperature, temperature gradient and the direction of heat radiation into the mattress. The result can be that the effects of radiation on the skin of newbornsPublication Metadata only A hybrid finite difference-finite element method to incorporate topography for 2D direct current (DC) resistivity modeling(2010-12-01) Chatchai Vachiratienchai; Songkhun Boonchaisuk; Weerachai Siripunvaraporn; Mahidol University; ThEPFinite difference (FD) and finite element (FE) approximations are two commonly used methods for solving Poisson's equation from a known electrical resistivity model. FD discretizes the model with rectangular blocks, while FE discretizes... it with right triangular elements. The advantage of FD is that it requires less computational time and memory storage, while the advantage of FE is its ability to handle topography. Here we introduce a hybrid FD-FE algorithm which requires less computationalItem Metadata only Mathematical model and numerical technique of blood flow in the system of human coronary arteries with no graft and with a bypass graft(Mahidol University. Mahidol University Library and Knowledge Center, 2023) Buraskorn Nuntadilok; Benchawan Wiwatanapataphee; Tang, I. Ming; Meechoke ChuedoungPublication Metadata only Study of geometric effects on nonpneumatic tire spoke structures using finite element method(2020-01-01) Ravivat Rugsaj; Chakrit Suvanjumrat; Mahidol University© 2020, © 2020 Taylor & Francis Group, LLC. This research aims to develop a finite element model of nonpneumatic tires (NPTs) with different spoke shapes to study the geometric effects on the NPT for the maximum stiffness and minimum local stress..., the shape with less complexity and simple patterns. The finite element models of NPTs with different four spoke types were created using the same tread, shear band and the overall dimension. The spoke component of each model was created using 2D elementsPublication Metadata only Analysis of heat transfer and specific absorption rate of electromagnetic field in human body at 915 MHz and 2.45 GHz with 3D finite element method(2012-12-01) W.
