Numerical simulation for the flexural response of large-span UHPFRC prestressed composite box girder
The study aims to provide an in-depth awareness of the loading capacity, deflection characteristics, and failure mechanisms exhibited by these girders by applying finite element analysis (FEA) techniques.

In the present paper, by using the higher-order shear deformation theory and the strain-displacement relationships of large deflection, the postbuckling analysis of the functionally graded graphene-reinforced composite laminated (FG-GRCL) parabola, sinusoidal, and cylindrical externally pressured panels is presented in detail.

In this work, geometrically nonlinear behavior of sandwich composite beams reinforced by carbon nanotubes is studied, taking into account the influence of agglomeration of the carbon nanotubes (CNTs). The core of the sandwich beams is homogeneous while the two face sheets are made of CNT reinforced composite with the effective material properties being estimated by the Eshelby-Mori-Tanaka approach.

This paper presents a novel design of the microactuator with a double stepped beam structure for large out-of-plane deflection output applied to microvalves. The design and analysis of the out-of-plane microactuator are implemented by the finite element method. Silicon is selected as the material of the actuator and the beam motion is generated by the Joule heating effect.

Large deflections of FG-CNTRC sandwich beams partially supported by a two-parameter elastic foundation are studied in this paper by a nonlinear finite element procedure. The core of the beams is homogeneous while the top and bottom are of CNTRC material.

In this paper the smoothed strain based four-node flat element MISQ24 with driiling degrees of freedom is extended for geometrically nonlinear analysis of plate and shell structures. The von-Karman's large deflection theory and the Total Lagrangian (TL) approach are employed in the formulation of the elements to describe small strain geometric nonlinearity with large deformations using the first-order shear deformation theory (FSDT).

In the present work, the large displacement behaviour of FGSW beams in thermal environment is studied by a finite element formulation. The beams considered herein consist of three layers, a homogeneous core and two FGM skin layers. The material properties are assumed to be temperature dependent, and they are graded in the thickness direction by a power gradation law. Based on Antman beam model, a nonlinear beam element using linear interpolation is formulated in the context of the total Lagrange formulation.
