A finite element model using a multi-fiber approach is proposed in this paper for the analysis of reinforced concrete (RC) members using fiber-reinforced polymer (FRP) reinforcements, with a specific focus on the effect of pure torsion. The proposed model is formulated using a displacement-based approach and a kinematic assumption involving a twonode Timoshenko beam.

This article presents two methods to determine pressing forces to the M1 copper plate. The first approach employs the upper-bound method, and the second method combines numerical simulation with a central composite design. The upper-bound method uses physical analysis to determine the deformation zone and establish the division of the rigid block model. The findings were identical to the slip-line solution method.

Ebook "Structural concrete: Finite-element analysis for limit-state design" is a review of available experimental data on the behaviour of concrete at both the material and structural levels reveals the unavoidable development of triaxial stress conditions prior to failure which dictate the collapse and ductility of structural concrete members; moreover - and in contrast with widely-accepted tenets - it can be shown that the post peak-stress behaviour of concrete as a material is realistically described by a complete and immediate loss of load-carrying capacity.

The present paper considers the composite plate resting on an elastic pinned subjected to harmonic loads. The plate element model with high-order shear deformation theory and finite element algorithm is proposed in order to buckling analysis of the plate. As a result, the buckling domain is determined. Moreover, the effect of geometric parameters, elastic pins, and materials on the buckling of the plate is comprehensively investigated.

In the present paper, a 2D nonlinear beam element based on the geometrically exact formulation for large displacement theory of beams developed by Zienkiewicz [7] is formulated on the basis of the first-order shear deformation theory and the total Lagrangian method. The displacements of the element are described through the original (reference) configuration.

This work uses the finite element method for the first time to simulate the dynamic response of nanoplates resting on a two-parameter elastic foundation under the flexoelectric effect. The calculation formulas are derived from the new type of the shear deformation theory, which is a simple shear deformation theory.

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.

In this paper, geometrical nonlinear flutter analysis of functionally graded carbon nanotubes reinforced composite plates is presented. The governing equations of the system are obtained using the Mindlin plate theory and von Karman geometric nonlinearity. The linear piston theory is utilized to determine the aerodynamic pressure. Applying the Hamilton principle, equations of motion of a system are derived in the matrix form, and then the finite element method is used to obtain the discretized equations.

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).

In the paper "Nonlinear static analysis of bidirectional functionally graded sandwich plates using a higher-order finite element formulation" the nonlinear static behaviors of bidirectional functionally graded sandwich (BFGSW) plates are investigated using a finite element procedure. The plates consist of three layers, a homogeneous core and two bidirectional functionally graded face sheets. A nonlinear finite element formulation in sense of the von Karman nonlinear strain-displacement relation is derived in the basis of a higher-order shear deformation theory.

In the paper "Finite element analysis for the composite sandwich plate using the homogenization method", we propose a homogeneous model for the composite sandwich plate. Accordingly, the 3D plate model will be replaced by a 2D homogeneous panel. Analytical calculations were performed for both models. The proposed model is confirmed by comparing the results obtained with the 3D plate model. The findings of this research will help us continue to build and finalize a homogenous model for a variety of structures.

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.
