3D finite element

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.

This paper presents a developed three-dimensional (3D) finite element model (FEM) of flexural and shear strengthening of reinforced concrete (RC) T-beams using a CFRP (Carbon Fiber-Reinforced Polymer) system combined by near-surface mounted (NSM) strips and U-wraps subjected by asymmetric loading. The 3D FEM was verified by experimental results.

This study is directed to understand the origin of that difference with a numerical simulation of the process. The mechanical behaviour of the materials was investigated in tension and hydraulic bulge test, out of comparison’s sake and to derive the hardening law over a strain range representative of the process. Finite element simulations are performed using the von Mises criterion coupled with isotropic hardening, to compare the predicted forming load and springback parameters with experimental values.

This article aims to present a numerical analysis of blood flow in the aortic valve using fluid-structure interaction simulation. The finite element method is employed both for fluid and solid domains, and the monolithic scheme is used for the strong fluid-structure interaction coupling to solve well the two challenges: add-mass and large deformation problems.

Bioinspired structures are remarkable porous structures with great strengthto-weight ratios. Hence, they have been applied in various fields including biomedical, transportation, and aerospace materials, etc. Recent studies have shown the significant impact of the plastic 3D printed triply periodic minimal surfaces (TPMS) structure on the cement beam including increasing the peak load, reducing the deflection, and improving the ductility.

The dynamic analysis is a necessity in the design, manufacturing and maintenance of structures. The analytic solutions are not available for most practical cases and the Finite Element Method (FEM) is not reliable due to the joint problem, unclear loading, material properties and numerical error. In this paper, we present a way to find modes shape of 3D Frame by FEM program using Matlab.

For plate bending problems, using a plate theory to model thin plate structures is less computationally expensive than 3D modelling. The Kirchhoff-Love plate theory is appropriate for analysing thin plate structures. If the membrane deformation is ignored in the KirchhoffLove plate, each node has only one degree of freedom – the deflection.

This study proposes an alternative approach based on the deep learning paradigm working in a complementary way with conventional methods such as the finite element method for quickly forecasting the responses of structures under random wind loads with reasonable accuracy. The approach works in a sequenceto-sequence fashion, providing a good trade-off between the prediction performance and required computation resources.

In this paper, we compare two types of commonly used wheel-track interaction models for wheel-rail impact problems, i.e., a beam and a continuum finite element model. We first reveal the differences between the impact forces predicted by the two models due to a typical rail squat using a time-frequency analysis.
