In this study, it is split into two main steps. First, an analytical design is proposed to define the desired parameters with affects of different flux air gaps. Then, a finite element approach is introduced to simulate magnetic field quantities (such as inductance, fringing flux, magnetic flux density, electromagnetic force, current, voltage) of the SRs.

The paper "Static bending analysis of FGM stiffened plate resting on discontinuous elastic foundation" uses the finite element method to study the static bending response of stiffened FGM plates resting on a discontinuous elastic foundation. The structure is computed using the first-order shear deformation theory coupled with the four-node and two-node quadrilateral elements.

The present work shows a study on the interaction of incompressible fluid flow with an artificial heart valve using fluid-structure interaction (FSI) ) simulation. The finite element method (FEM) is employed both for fluid and solid domains. The strong coupling scheme is used for the coupling of fluid and structure to satisfy the kinematic and dynamic equilibrium conditions.

In this study, a surrogate model based on artificial neural networks (ANN) will be established to predict the mechanical behaviors of the plastic Primitive TPMS reinforced beams. Finite element analysis (FEA) simulation results of different numbers of reinforcement layers and volume fractions were adopted as the model data, the robust model have been owing to a hyperparameter tuning investigation.

The article "Static behavior of FGP half-annular nanoplates resting on elastic foundation using nonlocal elasticity theory" presents an algorithm finite element for static bending analysis of the functionally graded porous (FGP) half-annular nanoplate resting on the elastic foundation (EF) using nonlocal elasticity theory. The FGP materials with two-parameter are the volume fraction index (k) and the porosity volume fraction (5) in two cases of even and uneven porosity. The EF includes Winkler-stiffness (k₁) and Pasternak- stiffness (k₂).

Large deflections of functionally graded carbon nanotube-reinforced composite (FG-CNTRC) sandwich beams are studied in this paper by a nonlinear finite element procedure. The core of the beams is homogeneous while the two faces are of CNTRC material. The effective properties of the two CNTRC face sheets are determined by an extended rule of mixture. CNTs are reinforced into matrix phase through uniform distribution (UD) or four different types of functionally graded (FG) distribution, named as FG-X, FG-A, FG-V, FG-O.

The paper "Dynamic response analysis of nanobeams resting on elastic foundations" uses the finite element method to study the dynamic response of nanobeams resting on an elastic foundation, taking into account the flexoelectricity effect. Timoshenko's first-order shear deformation theory is used to derive the formulations of the beam's forced vibration equation. The proposed theory and mechanical model are verified by comparing the numerical results of this work with those of the published data.

The paper "The behavior analysis of bolted end-plate connections under static load by using finite element method" investigates the mechanical behavior of bolted end-plate beam-to- column connections with changes of thin of end-plate and size of bolts under bending moment. The finite element models are generated in ANSYS software, in specially all of meshes are hexahedral meshes as well as be continuous at welding. The results obtained from this study are validated based on three factors: loading capacity, moment resistance and joint rotation.

The eXtended Finite Element Method (XFEM) produces high effectiveness in analyzing the crack propagation in structures. In this approach, the crack is modeled through enrichment functions instead of explicitly represented on the geometry. This study presents an object-oriented program to simulate crack propagation in 2-dimensional structures.
