The finite element modeling is established for reinforced concrete(RC) beam reinforced with fiber reinforced polymer (FRP) using the serial/parallel mixing theory. The mixture algorithm of serial/parallel rule is studied based on the finite element method. The results obtained from the finite element simulation are compared with the experimental data. The comparisons are made for load-deflection curves at mid-span. The numerical analysis results agree well with the experimental results. Numerical results indicate that the proposed procedure is validity.

In this study, control samples of pine (Pinus slyvestris L.), beech (Fagus orientalis L.) and oak (Quercus petreae L.) species were obtained by using fi ber reinforced finger corner joints. Teknobont 200 epoxy and polyvinyl (PVAc) adhesives were used as glue. Bearing in mind the critical loads that may affect their use, experimental samples were tested under diagonal loads. Experimental samples were also analyzed by a computer program using the finite element method (FEM). Finally, experimental data were compared with the results of FEM. The comparisons clearly showed that experimental results and finite element solutions (SAP2000 V17) including semi-rigid connections are in good agreement. As a structural analysis program in furniture engineering designs, FEM can be preferred in terms of reliability and cost.

The paper describes the results of a numerical study using Galerkin’s finite element method on an infinitely wide slider bearing. The analysis is based upon the generalized Reynolds equation with the assumption that the pressure gradient in the lubricating film is negligible in the axial direction. Detailed results for bearing characteristics including pressure, load capacity, frictional force, frictional coefficient as a function of film thickness ratio (aspect ratio), and velocity of slider show that these parameters have a strong influence on the bearing behavior. Specifically, it has been shown that friction coefficient and frictional force increases with lower aspect ratios. Also, higher load carrying and maximum pressure is obtained with increased speed of the slider Point wise comparison of the results obtained using the Finite Element Method and that obtained with second order Finite Difference marching Method using base parameters show that the latter simulation has a maximum point wise error of 0.46% in comparison to 0.32% for Finite Element simulation. It has been shown that the Finite Element Method produces more accurate results. The results are in tabular and graphical forms.

This paper presents a numerical method and computational results for acoustic noise of electromagnetic origin generated by an induction motor. The computation of noise incorporates three levels of numerical calculation steps, combining both the finite element method and boundary element method. The role of magnetic forces in the production of acoustic noise is established in the paper by showing the magneto-mechanical and vibro-acoustic pathway of energy. The conversion of electrical energy into acoustic energy in an electrical motor through electromagnetic, mechanical, or acoustic platforms is illustrated through numerical computations of magnetic forces, mechanical deformation, and acoustic noise. The magnetic forces were computed through 2D electromagnetic finite element simulation, and the deformation of the stator due to these forces was calculated using 3D structural finite element simulation. Finally, boundary element-based computation was employed to calculate the sound pressure and sound power level in decibels. The use of the boundary element method instead of the finite element method in acoustic computation reduces the computational cost because, unlike finite element analysis, the boundary element approach does not require heavy meshing to model the air surrounding the motor.

Recently, glass fiber reinforced polymer plastic (GFRP) pipes are widely used in the water-supply system because of their advantages such as light-weight, corrosion resistance, etc. In previous study, we present the equation to predict stiffness factor (EI) of GFRP pipe with two tape-winding FRP layers and polymer mortar layer in between two FRP layers. As a result, it was able to predict in the range of -3% to +7%. In addition to previous study, we attempted to predict stiffness factor (EI) of GFRP pipe by the finite element method (MIDAS Civil 2016). From the study it was found that the finite element method can be used to predict the pipe stiffness of GFRP pipe.

This paper deals with the problem of the front end bending arising in plate rolling. The problem, which is caused by unbalanced rolling, is investigated by the finite element simulation technique. Discussions are made on the effect of various unbalanced rolling conditions on the deformation of the front end. In particular, an empirical model is developed for the prediction of the curvature of the front end rolled under the presence of the roll speed difference.

The finite element method is used to simulate the optical coherent elastic imaging in Agar. The shear wave velocity in Agar was measured by ARF-OCE system, and then the Agar model was established by finite element method, and then the shear wave velocity in Agar model was measured. The shear wave velocity in experiment and finite element simulation were compared and analyzed. The shear wave velocity obtained in the experiment is 2.50 m/s, and the range of shear wave velocity obtained in the finite element simulation is 2.4802m/s, and the average wave velocity is 2.5167m/s. The finite element method can express tissue elasticity directly and clearly, and it plays a great guiding role in corneal elastography.
