“…The finite element method (FEM) is a numerical scheme to solve boundary value problems via integration over the weighted variational form of governing equations [1]. Since its introduction, FEM has been mainly applied in the analysis of structural engineering, such as welding analysis [2], machining of composite materials [3], buckling analysis [4], mechanical vibration [5,6], design of biomedical structures [7,8], and fatigue prediction of structures [9,10]. FEM has been well developed in solving structural mechanics, and much commercial software such as COMSOL® and SolidWorks® are constructed thereunder.…”

The finite element method (FEM) is a robust and widely applied numerical scheme in the simulation of engineering problems, especially in structural mechanics. However, FEM is not as popular as the finite volume method (FVM) in Computational Fluid Dynamics (CFD), possibly due to its complicated numerical procedures. Indeed, FEM possesses tremendous advantages compared with FVM, particularly in dealing with complex geometry and rendering attractive flexibility to modify the interpolation functions. It is well-known that FEM and FVM differ in mathematical formulation, yet there is a lack of practical comparison between them. Therefore, the paper aims to develop a Galerkin FEM (GFEM) model, investigate its strengths and weaknesses compared with FVM, and discuss the conciliation between FEM and FVM. Our case study focuses on a two-dimensional diffusion problem comprising steady and transient cases, with and without heat generation. Our investigation revealed that GFEM does not possess conservative properties, which might yield spurious heat flux, leading to a 2 – 4% overestimation of the temperature field, depending on the amount of heat generation. Moreover, GFEM incurs approximately 34% higher computational time than FVM. However, FVM can be perceived as a special form of GFEM, and their relations were discussed.

The world's oil and gas sectors are diverse. They utilize offshore pipes to generate millions of barrels of oil and gas to meet global energy demands. In this study we identified the critical buckling load that occurred on a cylinder shell (also known as radial buckling). Offshore pipe design must meet several criteria, one of which is the requirement for pipes to withstand the external hydrostatic pressure of seawater. The overall buckling load is calculated using the axial compression loading and the pressure on the entire surface of the cylinder shell (radial compression). The finite element analysis (FEA) method is used in our simulation. FEA is run using ABAQUS/CAE software with the Riks algorithm. Different types of cylinder shells are used in the simulation: unstiffened, stringer-stiffened, and ring-stiffened. The cylinder shell is loaded based on the depth of the installation. The material composition of the shell is varied with API 5L X65, copper-nickel alloy, and HY100 steel. The diameter sizes used are 28" (711.2 mm), 30" (762 mm), and 32" (812.8 mm). The simulation results show a critical buckling load for each variation. The critical buckling load is determined by the Young's modulus, geometric length, and moment of inertia. Based on the critical buckling loads generated, we also identify which cylinder shell composition is the strongest.

“…The motion of the offshore platform will drive the cyclic movement of the pipeline, which leads to the riser bearing the cyclic load, and the loading sequence of external water pressure and axial tension is constantly changing [9][10][11][12]. The sandwich pipe has good thermal insulation performance and structural strength, can resist high external water pressure, and is gradually being valued and applied in deep-sea engineering [13][14][15][16]. The ultimate bearing capacity of the sandwich pipe will be reduced under the action of tension loads, which will cause local instability of the pipe.…”

In this paper, the effects of different loading paths of axial tension and external pressure on the collapse pressure of sandwich tubes are studied by experiments and finite element models. The difference of the two loading paths is investigated. Eight experiments were carried out to study the influence of different loading paths on pipeline collapse pressure under the same geometric and material parameters. Parameterization studies have been carried out, and the results are in good agreement with the experimental results. The test and finite element results show that the loading path of external pressure first and then the axial tension (P→T) is more dangerous; the collapse pressure of the sandwich pipe is smaller than the other. Through parametric analysis, the influence of the axial tension and the diameter-to-thickness ratio of the inner and outer pipe on the collapse pressure under different loading paths are studied.
